3  vLoc-9800 Receiver Page 11 of 50 vLoc-9800 Receiver      3.1  vLoc-9800 Receiver The vLoc-9800 is a Precision Location System designed to meet the needs of Utility Companies and their contractors. The following describes the features and use of the receiver:     1 Bluetooth Module (Not available for vLoc-9800) 6 Charging Socket 2 Pushbutton & Display 7 Mini USB Port Data Transfer and Software Upgrade 3 Carbon Fiber Reinforced Antenna Assembly 8 Accessories Port 4 Accessory & Charging Sockets 9 Model# & Serial# 5 USB Data Transfer (Inactive) 10 AA Battery Pack/Rechargeable Battery Pack
3  vLoc-9800 Receiver Page 12 of 50 3.2  Charging the Receiver Batteries The  vLoc-9800  can  be  used  with  either  alkaline  batteries  or  it  can  be  supplied  with  an  interchangeable rechargeable battery pack.       When alkaline battery is used, Icon A will appear on the screen. When the rechargeable battery pack is used, Icon B will be displayed.  In  both  cases,  the  number  of  bars  illuminated  within  the  battery  icon  indicates  the  amount  of  charge remaining.  Rechargeable batteries are supplied with a mains charger. This is specific to the batteries, avoid the use of other manufacturers’ chargers as these may damage the battery pack and may result in overheating of the battery pack.  To charge the rechargeable batteries, first make sure the pack is inserted in the receiver battery compartment as charging is done inside the receiver.  Connect the charger to the charging socket of the receiver. Connect charger to the mains and switch on. The LED indicator on the charger will illuminate red until the batteries are fully charged at which time the LED will change to green.   WARNING Rechargeable batteries are supplied with a mains or 12V DC charger. These are specific to the batteries. Only use the charger that is appropriate for the batteries in the product. If in doubt, call Vivax-Metrotech Customer Service. Failure to use the appropriate charger could result in damage to the battery pack, locator and in extreme cases cause fire.  Avoid charging the unit in extreme temperature conditions. (i.e. below 0ºC and above 45ºC)  Although  Vivax-Metrotech  batteries  include  all  the  required  safety  related features always immediately discontinue use of the charger and battery pack if the  battery  pack  becomes  excessively  warm.  Return  both  to  where  they  were purchased for investigation.  Always ensure batteries have at least a partial charge if storing for long periods without use.  Dispose  of  all  batteries  in  accordance  with  your  company  procedures  and Federal/State and local regulations.  Never dismantle batteries, put them in fire, or get wet.       Icon A    Icon B
3  vLoc-9800 Receiver Page 13 of 50 3.3  vLoc-9800 Receiver Display The vLoc-9800 has two operational displays, “Left/Right” and “Peak Detect”.    1 Sensitivity Setting 8 Signal Strength 2 Auto/Manual/Sonde Indicator  9 Mode Select, Auto/Peak/Sonde 3 Frequency 10 Increase Sensitivity 4 Speaker Volume 11 Change Frequency 5 Battery Level 12 Information Key (selects depth screen for instance) 6 Signal Strength Bar Graph 13 Reduce Sensitivity 7 Moving Pointer 14 On/Off Switch  3.4  Locating Mode (Response) The  vLoc-9800  receiver  has  an  array  of  antennas;  these  can  be  toggled  through  different  configurations (modes) to provide different responses to the signals radiating from the buried pipes and cables. The modes are:  3.4.1  Auto Left/Right Mode    The Left/Right Auto mode is ideal when tracing long distance lines in less congested sites. It requires no user input to the keyboard allowing the operator to concentrate more on the safety of the surroundings.  Left/Right Display Peak Detect Display
3  vLoc-9800 Receiver Page 14 of 50 As the locator is moved from left to right across the cable the moving bar will move accordingly. When the moving bar is directly over the circle (indicating the cross section of a cable or pipe), the locator is directly over the target line. At this point the numeric signal level will be at its highest.   NOTE The tone from the speaker is pulsing one side and has a solid tone the other. This  is  to  enable  the  operator  to  easily  judge  the  position  of  the  line without looking down at the display when walking along busy streets etc.  When operating in the Auto Left/Right mode the dB sensitivity value will be continuously changing. This is because the  unit is automatically adjusting the  gain of the  instrument to  optimize the  performance in  that situation.  3.4.2  Manual Left/Right Mode (Available on some models)  In the Manual Left/Right  mode  the sensitivity  is  set  by pressing the “+”  and  “-”  pushbuttons. This has the advantage of enabling the operator to adjust the sensitivity balance on signals from a deep pipe or cable.  It can also be used to mask out the signal from an unwanted source.  To  reject  an  unwanted  signal,  first  set  the  sensitivity  to  a  high  value  such  that  the  unwanted  signal  is detectable. Sweep across the unwanted signal, reducing the sensitivity until the locate bar ceases to respond to the signal. Now double check that the wanted line is detectable. Keep the sensitivity at this setting and continue to locate the line.  3.4.3  Manual Mode    The Manual mode is particularly useful in congested areas where there are multiple signals radiating from various  lines.  The  sensitivity  is  set  manually  by  pressing  the  “+”  and  “-”  pushbuttons.  As  the  locator  is traversed across the target line the “curtains” of the bar graph will close. If the curtains are fully closed or fully open,  one  press  of  the  “+”  or “-”  will  bring  the  curtains  back  within  scale.  A  numeric  signal level  is  also displayed.  When using the manual mode the relative signal levels become apparent aiding identification of the target line.
3  vLoc-9800 Receiver Page 15 of 50 3.4.4  Sonde Mode     Sonde mode uses the antennas in a “Peak” configuration. Text on the display indicates if the receiver is in Sonde mode.   A Sonde is a small transmitting coil that is powered by its own internal battery, or by an external transmitter.  Due to its construction, a Sonde gives a different “Peak” pattern – when locating along the direction of the Sonde – instead of the usual single “Peak”, the Sonde provides three distinct peaks – a small “Peak” – a large “Peak” – a small “Peak”. The Sonde is located under the center of the large “Peak” when located across the direction of the Sonde and it gives the conventional peak response.  The vLoc-9800 receiver must be used in a different orientation when locating a Sonde – due to the way the signal  from  the  Sonde  radiates.  With  the  front  of  the  receiver  pointing  across  suspected  direction  of  the Sonde – pinpoint forward and backward (across the Sonde) and then move along the line of the Sonde until the maximum peak is located (in other words rotate the receiver 90º from the orientation normally used when locating pipes and cables).  A Sonde is typically used for locating non metallic pipes or ducts, and the camera end of a sewer inspection camera. Low frequency versions (512Hz/640Hz) can transmit through some metallic pipes such as cast iron pipes – which is why they are frequently used with sewer inspection cameras.  3.5  Audio  The visual display is also accompanied by an audio response. The output level (volume) of this response is set  by  entering  the “Menu”. Press  and  hold  “i” pushbutton for  2 seconds to  enter setup menu. The setup display defaults to volume. Use the “M” pushbutton to toggle through the available options (Off – Low – Med – High). Press the “i” pushbutton again to exit the setup menu. As the loudspeaker uses a significant amount of power, using lower volume can make the battery life of the receiver last longer.  3.6  Sensitivity Control    In manual modes, up & down pushbuttons are provided to increase or reduce the sensitivity of the receiver. If the bar graph moves towards the minimum or maximum a single touch of the opposite pushbutton returns it to  approximately  50%  deflection.  Holding  down  or  repeated  pushing of  the  “+”  or  “-”  pushbuttons increments/decrements the gain.   Pushbutton            Pushbutton
3  vLoc-9800 Receiver Page 16 of 50 3.7  Setup Menu        A  second  function  performed  by  the  “i”  pushbutton  is  to  access  the  setup  menu.  Press  and  hold  the  “i” pushbutton  for  two  seconds  to  display  the  setup  menu.  Use  the  “+”,  “-”  to  navigate  through  the  various options and use the “M” pushbutton to select. To exit the setup menu, press the “i” pushbutton.  The setup menu allows the user to configure their personal preferences. This menu can be accessed and changed at any time.  3.8  Frequency Selection        The vLoc-9800 receiver is capable of locating a number of frequencies. A list of these frequencies can be accessed using the setup menu. The setup menu allows the operator to select the frequencies they wish to use  regularly.  The  frequency  select  pushbutton  on  the  main  receiver  pad  is  used  to  toggle  through  the frequencies defined in the setup menu. The operating frequency is shown in the information bar at the top of the display. It is possible to change this selection at any time using the setup menu.  The initial frequencies set at the time the unit is supplied are “Power”, “Radio”, 982Hz, 9.8 kHz, and 83.1 kHz. See the transmitter section for suggestions of which frequency is best suited to specific applications.  To select the frequencies you wish  to use regularly, enter the setup menu by pressing and holding the  “i” pushbutton for 2 seconds. Use the “+” and “-” to select the word “Frequency” – then press the “M” pushbutton to display the list of available frequencies.  The  “+”  and  “-”  pushbuttons  are  used  to  navigate  the  list  of  frequencies.  To  add  a  frequency  to  the “Frequently used list” press the “M” pushbutton and a dot will appear in the circle alongside the frequency. To deselect a frequency press the “M” pushbutton and the dot will disappear. Once your selection is completed press “i” pushbutton once to return to the setup menu, and again to exit the setup menu.  3.9  Information Pushbutton (Depth & Current)       Pressing the “i” pushbutton will display the depth to the center of the radiated signal and a measurement of the current (press the pushbutton briefly – remember if you press and hold, you enter the setup menu. If you do enter the setup menu, press the “i” pushbutton again to return to the locating screen then try again).  If measuring the depth of a Sonde, ensure “Sonde” mode is selected otherwise the depth measurement will be incorrect. Sonde mode has a different “Depth” screen and does not indicate current.  Pushbutton Pushbutton
3  vLoc-9800 Receiver Page 17 of 50  IMPORTANT When locating a cable or pipe (“Line”) – the instrument should be in “Peak” or “Left/Right”  mode  and  the  depth  and  current  measurements  should  only  be taken with the bottom of the receiver standing on the ground and directly in line with the target line.  When  locating  a  Sonde  –  set  the  mode  to  Sonde  -  then  the  instrument  will automatically  be in  “Peak” configuration. Depth measurements should only be taken  with  the  bottom  of  the  receiver  standing  on  the  ground  and  at  ninety degrees to the Sonde.  The accuracy of depth and current readings depends on the quality of the radiated signal being located. If the signal is not distorted, the  depth reading will be  accurate  to within 5% of the actual depth. If the signal is distorted, depth readings will be less accurate. When taking depth measurement, always hold the receiver in line with the line and at 900 to the ground.

Pushbutton  1 On/Off Control 2 Output Decrease 3 Frequency Select 4 Output Increase 5 Information (Volume, mAmps, volts, ohms)   Connections  1 Output Connection 2 Output Protection (Fuse) 3 Loudspeaker 4 Battery Charging Socket & DC Input
5  Loc-10Tx Transmitter Page 25 of 50 5.1.1  Transmitter Battery  In most markets the transmitter is shipped with alkaline batteries (12 x D cells) unless rechargeable batteries are  specified.  Batteries  are  fitted  into  quick  release  trays  –  the  alkaline  is  an  open  pack,  to  enable  the batteries to be changed. The rechargeable pack is  a sealed unit containing Ni-MH (Nickel Metal Hydride) batteries.  These  packs  can  only  be  fitted  in  a  manner  to  ensure  that  the  alkaline  batteries  cannot  be inadvertently charged.  5.1.2  Removing the Battery Tray    5.1.3  Replacing the Alkaline Battery   To access batteries – undo stainless steel screws on each battery cover   To remove batteries – turn tray upside down and give a short sharp tap of the battery tray on your hand   Replace  batteries  with  new  batteries  of  the  same  type,  be  sure  not  to  mix  old  and  new batteries   Do NOT use rechargeable batteries in the  alkaline battery tray. Ensure that batteries are inserted the correct way (see label and molded “+” and “-” in the bottom of the tray)   Refit the battery cover – then refit the battery tray   WARNING Alkaline Batteries – insert alkaline batteries (x12) as shown:   5.1.4  Rechargeable Batteries   Do NOT attempt to replace the rechargeable batteries or remove battery covers – return to Vivax-Metrotech or a Vivax-Metrotech approved service centers for replacement.   WARNING Use only Vivax-Metrotech recommended charger.  5.1.5 Re-fitting the Battery Tray  Place top of catch over catch plate Push up button underneath the catch – where holding that up push in the bottom of the catch. Push up button Pull out bottom of catch Lift up catch until it clears catch plate
5  Loc-10Tx Transmitter Page 26 of 50 You will hear a positive “click” (Do NOT force catches) To close battery tray – slid transmitter (TX) onto tray, it will locate itself in the correct position, then close the catches.   WARNING Power “IN” socket   Two pins are used for power in from charger (to charge rechargeable batteries). Two pins are used for power from external 12V DC source. A 12V DC power cable is supplied and is designed to be connected to an automobile cigarette lighter socket.  Contact  Vivax-Metrotech  or  a  Vivax-Metrotech  approved  service  center  for  wiring  diagram  of  plug,  if attempting to repair any of the “charging” leads.  5.1.6  Battery Charging and Disposal Follow instructions detailed in the General Safety & Care portion of this document. Only use the battery charger supplied. Using  a non  approved charger may damage the battery pack and could cause overheating.  To charge, the batteries must be connected to the transmitter. Connect the mains charger to the charging socket on the side of the transmitter and connect the charger to a suitable mains socket.  The LED will show a  red light indicating that the charge cycle is in progress. When the batteries are fully charged the LED will change to green.   NOTE Rechargeable pack cannot be charged from a 12V DC source.  5.1.7  Battery Condition Indication The battery condition (charge) is displayed on the left side of the display, in the case  of the rechargeable batteries the condition is also indicated on the charger (red/green light).  5.2  Transmitting Modes The transmitter has three transmitting modes, which are selected automatically.  5.2.1  Induction Mode This uses an internal antenna to induce a locating frequency onto the target pipe or cable (line). “Induction” mode is automatically selected  if no  connection accessories are plugged into the “output socket”. An  icon indicating “Induction” mode shows on the display. The icon flashes when the transmitter is transmitting. In order to generate successful induction, the transmitter should be positioned over and with the handle in line with the target line.  “Induction” mode  is  generally used  when no  access  is available to  make  a direct connection,  or  a  clamp connection. When using induction it is very likely that the signal being induced onto the target line will also be induced onto other lines in the area, and onto above ground features such as wire fences. This can influence the accuracy of the location, depth and current measurements. “Induction” mode is also the least  efficient Icon
5  Loc-10Tx Transmitter Page 27 of 50 way  of  applying  the  transmitting  signal  to  the  target  line.  The  distance  located  with  “Induction”  mode  is generally  much  less  than  that  achieved  with  a  direct  connection  or  clamp  connection.  “Induction”  mode generally works better in higher frequencies, 33 kHz, 65 kHz and either 83.1 kHz or 200 kHz (depending on region). The advantage of induction is that no access is required to “connect” the transmitter, making it a very quick  process.  The  antennas  on  the  transmitter  are  tuned  to  induce  specific  frequencies  or  range  of frequencies. Therefore only a limited number of frequencies can be selected in “Induction” mode.   NOTE For accurate location and depth measurement the locator receiver should be used no closer than 50ft (20m) from the transmitter.  5.2.2  Direct Connection Mode By  plugging  in  a  connection  lead  to  the  output  socket,  “Direct  connection”  mode  is  selected.  An  icon confirming this  is  shown  on  the  display.  The  icon  flashes  when  the  transmitter  is  transmitting.  The  direct connection lead consists of two cables, one (red clip) must be connected to the conductor being located, the other (black clip) to a suitable ground (a ground stake is provided with the transmitter). An auxiliary ground lead is also supplied. If the auxiliary ground lead is used, the ground clip of the connection lead (black clip) is attached to one end of the auxiliary ground lead.  Wherever a direct connection can be safely made without the risk of injury, damage to customer’s plant, or the transmitter, it is the best way of applying the transmitter’s signal.  The  coupling of  the  transmitted signal  to  other  pipes and  cables  in  the  area  will be  much  less  than with induction, although where commonly bonded systems are encountered – coupling cannot be avoided.  The  positioning  of  the ground  connection  can also  influence the degree  of  coupling experienced. Ground connections generally should not be made to other pipes or cables, or above ground metallic structures such as wire fences. In general the lower the frequency is, the further the signal will travel, and the less signal coupling will occur. The most common frequencies used for direct connection are between 512 Hz/640 Hz and 8 kHz.  Regulations in many countries require that power output is limited above certain frequencies. The Loc-10Tx enables frequencies below 45 kHz to be transmitted using as much as 10 watts output, but frequencies over 45 kHz are restricted to 1 watt. Using direct connection and the higher power at the low frequencies helps significantly in achieving greater location distances. Direct connections should not be made to cables carrying greater than 35 volts (or as your safety practices allow). The transmitter is protected (250V fuse) from stray currents that may exist on the target line.  5.2.3  Clamp Mode Plugging the signal clamp supplied by  Vivax-Metrotech  into the  output socket will  place the  transmitter in “Clamp” mode. An icon confirming this is displayed on the display. The icon flashes when the transmitter is transmitting. When using the clamp no ground connection is needed.   Icon Icon
5  Loc-10Tx Transmitter Page 28 of 50 The  clamp  again  is  a  precise  way  to  apply  the  locating  signal.  It  is  generally  used  when  access  to  the conductor cannot be achieved to make a direct connection (but there is sufficient access to place the clamp around the cable), or when it is not safe to make a direct connection because the target cable is carrying electricity.  The  clamp  is  a  specialized  inductive  device  (sometimes  known  as  a  toroid  or  coupler).  All  clamps  are optimized  to  work  at  specific frequencies.  In  most  cases clamps  are  designed  to  be  used  at  up  to  three frequencies  only,  generally between  8  kHz  and 85  kHz.  The  transmitter will  only  allow  the  selection  of  a suitable frequency for your clamp.   WARNING When applying the clamp to cables that  carry  electricity  – be sure  to follow your  company’s  safety  instructions  and  procedures.  Beware  that  if  applied around a high  voltage cable  – that cable may  induce a  current in  the clamp causing  it  to  snap  shut  or  jump  quite  dramatically  –  always  apply  clamps carefully.  5.2.4  Connection Block    1 Output Connection 2 Output Protection (Fuse) 3 Loudspeaker 4 Battery Charging Socket & DC Input   All the connections made to the transmitter are made at the connection block except for a USB socket which is mounted inside the battery compartment and is used for programming the transmitter’s processor.  The connection block consists of:   Output (XLR) socket – for the direct connection lead and clamp.   Charger  socket  (to  allow  the  retrofitting  of  a  rechargeable  battery  pack  –  the  charging socket is present even if re-chargeable batteries have not been purchased).   Transmitter  12V  DC  power  lead  used  to  power  the  transmitter  from  a  vehicle  (NOT  for charging).   Fuse – this protects the transmitter circuitry in the event of the transmitter receiving up to 250V incoming on the output leads.   A beeper is positioned behind the small hole.  5.2.5  Frequencies and Power Output The Loc-10Tx transmitter is supplied with a predefined set of transmit frequencies.  Standard frequencies are:   982Hz – 10 watts, 5 watts, 1 watts   9.80 kHz – 10 watts, 5 watts, 1 watts   83.1 kHz – 1 watt
5  Loc-10Tx Transmitter Page 29 of 50  As with most manufacturers the clamps and induction antennas are tuned to  specific frequencies, and do NOT work over the complete range.   Frequencies are selected by pressing the “f” pushbutton which toggles through the available frequencies for the selection mode. The frequency is automatically selected if you don’t toggle past it within 2 seconds. The frequency is shown on the display.  The output current is shown in large characters on the display – to increase or reduce the power output press “+” or “-”. The vertical bar graph at the bottom of the display indicates which of the four current output steps is being used. If the transmitter can supply the requested current, the bar will turn black. If the bar does not turn black, improving the ground connections or wetting the ground where the earth stake in positioned, may help. However, it may not be able to achieve the current setting requested because the impedance of the line is too high for this setting. If this happens it is best to select a setting that has a black bar, this will ensure a stable output.  The current being transmitted will be  limited by  the impedance of the cable, therefore it is  not unusual to increase the output level, but see no increase in the current displayed. This is not a fault with the transmitter.  The transmitter will always revert to first level output when switched on – this is a power saving feature – in most circumstances this output level is sufficient. Increasing the output power unnecessarily will reduce the battery life unnecessarily. All other settings remain the same as the last setting used.  5.2.6  Most Used Frequencies (Frequency Selection) Feature This  feature  can  be  used  to  allow  operator  to  choose  his  most  used  frequencies  from  a  list  of  possible frequencies. Once these frequencies are selected in the main menu, pressing the "f"  pushbutton, user can scroll through them. At any time user can add or remove frequencies from the above list, following the below procedure.  The advantage of this feature is that user can optimize the transmitter and activate at the main menu user’s preferred frequencies, instead of having a whole list of frequencies that user has to scroll through.  To enter the "Frequency Menu" proceeds as follows: 1.  Press the “i" pushbutton 5 times to get to the "Frequency selection" sub-menu.  2.  Screen will show a list of frequencies available, with the central one in a box.  3.  Pressing the "+" or "-" pushbuttons, you can scroll up or down through the available frequencies. 4.  Once the wanted frequency is inside the box, press “f” pushbutton to select or deselect the frequency. An “x” will appear in the box for a selected frequency.
5  Loc-10Tx Transmitter Page 30 of 50  5.  After selecting for the frequencies, press the "i" pushbutton again to exit the “Frequency Menu” and the selected list of frequencies can be select from the main display screen. Save and exit will automatically happen if there is no pushbutton press for about 5 sec while in the "Frequency Menu".  5.2.7  "Dual frequency" Mode This feature can be used when user wants to energize on user’s target two frequencies at the same time. Mainly, it can be used when user is not sure which frequency can be impressed better into the target.   NOTE  When using "dual frequency" mode, total power will be split between the two activated frequencies.  This mode of operation is available only for frequencies below 40 kHz.  The two frequencies have to be available in the main menu.  To enter the "Choose Second Freq." menu, proceeds as follows: 1.  Press "f" pushbutton to select the lowest frequency that user want to have in the dual combination. 2.  Press "i" pushbutton 4 times to get to the "Choose Second Freq." sub-menu. The above frequency will be shown in a box.  3.  By using  the "+"  and "-"  pushbuttons, user can  scroll through the  available frequencies and bring the wanted one in the box.  4.  Press "f" pushbutton to select the second frequency and exit the submenu to return to the main display. 5.  In the main display screen, both frequencies are displayed. The frequency will toggle between the two chosen frequencies.   NOTE If  user is  changing  the selected frequency  by  pressing  the "f" pushbutton, this mode  will  be  deactivated.  To  reactivate  it,  user  has  to  follow  again  the  above procedures. If  the  unit  is  powered  down,  this  mode  will  be  reset.  To  activate  it  again  after power up, user has to follow the above procedures.  5.3  Information   The digits in the center of the display default to output current (in mA).

6  Loc-5Tx Transmitter Page 36 of 50 6.7  Induction Mode This uses an internal antenna to induce a locating frequency onto the target pipe or cable (Line). “Induction” mode is automatically selected if no connection accessories are plugged into the “output socket”. In order to generate successful induction, the transmitter should be positioned over and in line with the target line.      “Induction” mode  is  generally  used  when  no  access  is  available  to  make  a  direct  connection,  or  a clamp connection. When using induction it is very likely that the signal being induced onto the target line will also be induced onto other lines in the area, and onto above ground features such as wire fences. This can influence the accuracy of the location, depth and current measurements. “Induction” mode is  also the least efficient way  of  applying  the  transmitting  signal  to  the  target  line.  The  distance  located  with  “Induction”  mode  is generally  much  less  than  that  achieved  with  a  direct  connection  or  clamp  connection.  “Induction”  mode generally works better in higher frequencies, 33 kHz, 65 kHz and either 83.1 kHz (depending on region). The advantage  of  induction  is  that  no  access  is  required  to  “connect”  the  transmitter,  making  it  a  very  quick process. The antennas on the transmitter are tuned to induce specific frequencies or range of frequencies. Therefore only a limited number of frequencies can be selected in “Induction” mode.   NOTE For accurate location and depth measurement the locator receiver should not be used within 50ft/(20m) meters from the transmitter.  6.8  Direct Connection Mode A connection lead set is supplied with the Loc-5Tx transmitter. This lead set is used to make an electrical connection to a cable or pipe that is to be traced. One of the leads is connected to the line and the other to a ground point that is nearby or a by inserting the ground rod supplied with the equipment and connecting to that.  A good connection is indicated by a change in tone from the speaker and a current reading on the display.  More information can be found in section 5.2.2  6.9  Clamp Mode The signal clamp is an optional extra. There are three different sizes 2in (50mm), 4in (100mm), 5in (125mm), 18in flexible (450mm).  The clamp is  generally used to apply the signal tone to a  live cable or telecom cable where an  electrical connection is not possible because of safety or access issues.  Please refer to section 5.2.3 for further information.

This is covered in section 6.7 to 6.9.
8  Using the vLoc-9800 Page 38 of 50 Using the vLoc-9800      8.1  Using the Receiver 8.1.1  Line Locating Line  locating is  a  term  used to  describe  the action  of  locating the  position  of  a  pipe  or  cable. When line locating, the receiver should be held with the display forward, and then swept to the left and right, across the suspected direction of the buried line. The largest signal will be detected when directly over the line. If the direction of the line is known it should be possible to trace the route using the Left Right Auto mode. If in doubt, switch to the manual mode to confirm the position and direction. The Auto and Manual modes are explained in more detail in Section 3.    The receiver should be kept parallel to the ground – and should not be flipped up at the end of each pass. See diagram (a).  To establish the direction of the cable – use the “M” pushbutton to select the Manual mode. Pinpoint the line – by carefully establishing the exact “Peak” position. Then (with the base of the receiver on the ground) rotate the receiver through 90 degrees, as you do this the signal being received will reduce substantially (possibly disappear). Then rotate the locator until you find the maximum “Peak”. The front of the locator is again facing in the direction of the buried line. See diagram (b).  8.1.2  Depth & Current Measurement Pinpoint the exact position of the cables as above:    Once the position and direction of the cable has been established, stand with the base of the locator on the ground – with the locator in the absolute “Peak”  position (over and in line). Then press the “i”  information pushbutton briefly, the current and depth will be displayed.
8  Using the vLoc-9800 Page 39 of 50 8.1.3  Sonde Location This is used for locating a Sonde only. A Sonde is a transmitting coil and the signal radiates in a different manner than that of a line (see diagram b).   Note that there are 3 distinct peaks: a small peak, a large peak, a small peak. The Sonde is located under the center of the “large peak”. When locating across the direction of the Sonde it provides the conventional peak response.  A Sonde is typically used for locating non metallic pipes or ducts, and the camera end of a sewer inspection camera. Low frequency versions (512Hz/640Hz) can transmit through some metallic pipes such as cast iron pipes – which is why they are frequently used with sewer inspection cameras.  Ensure Sonde mode is selected as depth measurements taken from a Sonde in any mode other than Sonde mode will be inaccurate.  8.2  Passive or Active Location There are two types of location method available with this system, they are:  8.2.1  Passive Locating Passive locating of buried utilities uses electromagnetic signals that exist in the environment. We group these under two settings:    Power  (P)  –  these  are  signals  that  generally  originate  from  electrical  power  generation systems. These are around 50/60Hz and their associated harmonics.   Radio  (R)  –  these  are  signals  that  generally  originate  from  low  frequency  radio transmissions. These are generally in the range of 16 kHz to 22 kHz.    Passive location is used to search an area to see if buried metallic lines are present (known as locating to AVOID). It does not help to identify what buried pipe or cable is present, only to confirm that there is a pipe or cable there. A typical application would be to check an area before installing a fence post.   NOTE Passive locating can only be done in the manual mode. (a) (b)
8  Using the vLoc-9800 Page 40 of 50 8.2.2  Active Locating  Active locating is using a transmitter to apply a very precise frequency to a pipe or cable, and then using a receiver turned to find the signal being radiated at that precise frequency. Active location frequencies can be applied by direct connection, clamp or induction.  This transmitter operates at a range of frequencies for active location.   The choice of frequencies when using induction or the clamp is restricted due to the requirement that these modes be tuned for specific frequencies (or range of frequencies). The full range of frequencies is available in “Direct connection” mode.  For  frequencies  below  45  kHz,  authorities  such  as  the  FCC  allow  higher  power  output  to  be  used;  for frequencies of 45 kHz and above, power output for this type of equipment is restricted to 1 watt. Therefore more power is available when lower frequencies are used.  8.3  Applying the Transmitter’s Signal The transmitter’s signal cable is applied in any one of the three ways:  8.3.1  Direct Connection This  is  used  on  pipes  or  cables  that  are  not  live  and  do  NOT  carry  hazardous  voltages.  The  “Direct connection” mode will be selected automatically when the connection leads are plugged into the transmitter.    WARNING Never make a direct connection to live cables carrying hazardous voltages.  Do NOT plug the connection leads into the  transmitter before connecting to the  buried  line and fixing  the ground stake.  Take the ground stake and push firmly into the ground and connect it to the black connection lead.  To make the signal travel further  along the  buried line,  ensure to  place the  ground stake  as far  away as possible, and at 90 degrees to the line. Where practical avoid having other buried lines between the ground stake and the target line, this will reduce the chances of the transmitter signal coupling to another pipe or cable.   Do NOT connect the black lead to any other metallic items that may have an above or below ground structure, or  to  any  other  pipes  or  cables;  connecting  to  such  items  would  cause  signals  to  radiate  from  these secondary structures, which in turn will increase the likelihood of an incorrect locate.
8  Using the vLoc-9800 Page 41 of 50 Connect the red connection lead to the target line after removing any surface corrosion.  Plug the connection leads into the transmitter switch on and select the desired frequency.   WARNING BE CAREFUL not to hit other buried lines when inserting the ground stake into the ground. Check using passive location prior to inserting ground stake. Stop if additional resistance is felt during insertion.  8.3.2  Clamp (Coupler) This is used  when applying  the transmitter signal to  cables carrying  hazardous voltages, or cables where access to the metallic conductor is not possible, or  desirable. The “Clamp” mode is selected automatically when the clamp is plugged into the transmitter.    For a clamp to work the current induced by the clamp must flow along the buried line. This means the buried line must have a ground connection at both ends.  Do NOT plug the clamp into the transmitter before applying it to the target line. Open the jaws of the clamp, place around the target line, close the jaws. Be sure that the jaws of the clamp are completely closed. After applying  the  clamp,  plug  it  into  the  transmitter,  switch  on  and  select  the  required  frequency.  Clamps  are generally turned to specific frequencies. Your transmitter only allows frequencies that are compatible with the clamp to be selected.  Please note – at the end of the clamp, and in the area close to the clamps hinge the exposed end of the clamp laminations can be seen. Any dirt or corrosion on these ends will reduce the efficiency of the clamp.   WARNING ALWAYS follow the appropriate safety requirements mandated by safety legislation, safety practice or your company’s safety procedures when applying a clamp (coupler) to a cable. BEWARE that when placing a clamp around cables carrying high current, the clamp may vibrate, jump or close violently due to inducted current from the target cable.  8.3.3  Induction This is used when no connection via direct connection leads, or coupler is possible. If no connection leads or clamp are connected to the transmitter, it will automatically select “Induction” mode.  An induction loop is fitted inside the handle of the transmitter. The transmitter must be placed over the target cable with the handle over and in line with the target pipe or cable. The induction loop is tuned to operate at specific frequencies. Only these frequencies can be selected when in “Induction” mode.  Do NOT place the transmitter on a manhole cover, or any other such metallic object, as that object will shield or soak up the signal resulting in little of no signal being induced in the target line.
8  Using the vLoc-9800 Page 42 of 50 When using the “Induction” mode to apply a signal to a line, ensure that a minimum distance of 50ft (20m) is maintained. This is because the transmitter will transmit signal through the air which will interfere with signals from the cable, resulting incorrect information.    8.3.4  Searching (sweeping) an Area In any given area, it is likely that buried pipes and cables are not parallel to each other, frequently they will cross  the  area  being  searched  at  a  variety  of  different  angles  and  depths.  As  the  response  of  locator antennas is directional, it is important to search the area in the same or similar pattern as below. This orients the antennas in  a way that will  locate any signals  being  radiate  from  the buried line. Once  a response is found,  then  trace  and  pinpoint  the  line  and  mark.  Searching  an  area  in  this  way  is  generally  (but  not exclusively) done in the “Peak” mode using passive locating.   8.3.5  Tracing a Buried Line Once  a  buried  line  is  located  it  is  generally  necessary,  and  a  good  practice,  to  trace  that  line  for  some distance  in  both  directions.  Whenever  practical  it  should  be  traced  to  a  point  that  provides  additional confirmation of what type of service is being located (a telephone pedestal, a manhole cover etc). If tracing a line to which a transmitter signal has been applied, one should trace out from the transmitter connection point. The receiver should be held level to the ground and rotated in a small arc across the anticipated route of the buried line. A clear response should be visible on the display and heard audibly.
8  Using the vLoc-9800 Page 43 of 50 8.3.6  Pinpointing & Confirming the Buried Line Marking the exact position of the buried line is generally called pinpointing. Pinpoint the line before marking its position. Place the receiver in “Peak” or “Left/Right” mode, pass the blade of the receiver across path of the cable and identify the peak response on the display and/or audibly.   8.3.7  Distorted Fields When locating always be aware that you are locating the signals radiating from the buried line, and these radiated fields as they are called can be distorted by other lines or electromagnetic buried lines or metallic features like crash barriers or wire mesh fences. The risk of an inaccurate location can be reduced further by the following:    To check if the signal is being distorted by other radiated fields. First locate the cable in the either mode. Place the locator on the ground and take a depth reading by pressing the “i” pushbutton.  Note  the  result  and  then  raise  the  locator  approximately  1.5ft  (0.5m)  Take another  depth  reading  and  check  the  depth  has  increased  by  this  amount. If  it  has,  the depth is likely to be correct. If it has not, then the depth is not likely to be correct because the signal is distorted.  8.3.8  Measuring Depth and Current   Pinpoint  the cable  as  described  in  “Pinpointing cable”,  with  the  receiver  in  line  with  and directly above the  buried line  –  measure the depth  (d) by  pressing “i” pushbutton  briefly. Current will be displayed at the same time as the depth.   Be  careful  when  locating  in  congested  areas  or  close  to  bends  or  tee’s,  they  may  be inaccurate due to distorted fields.     An  alternate  method  of  verifying  depth  (D)  is  triangulation  which  can  be  done  in  the “Peak“ modes
8  Using the vLoc-9800 Page 44 of 50    Measuring the signal current. Pinpoint the line as for measuring depth. The current can be displayed  by  briefly  pressing  the  “i”  pushbutton.  Depth  and  current  will  be  displayed  the signal from the transmitter will attenuate with distance. The further from the transmitter the less signal will radiate from the buried line. By locating at several points along the buried line you will identify an approximate rate of signal loss (beware that where a pipe or cable divides  the  signal  will  reduce  more  rapidly).  If  the  signal  current  at  the  point  you  are pinpointing is different from the trend would suggest, check to confirm that the correct cable is  being located.  To do  this  return to  a  point where  the  current is  as  expected  and very carefully  trace  the  line  to  the  new  location  checking  regularly  that  the  current  has  not changed  significantly.  A  sudden  change  in  current  may  be  caused  by  straying  onto  an adjacent line.   WARNING NEVER mechanically dig over the path of a buried pipe or cable. ALWAYS dig carefully.  8.4  Using the Accessories 8.4.1  Using the LPC Separation Filter  The LPC separation filter  (LPC) is  used to  safely inject a trace tone to a live cable via a domestic mains socket, so that the cable can be traced from the premises to the connection in the street. It is suitable for connecting to voltages between 100V AC and 250V AC.  Method: Plug the LPC into the output socket of the transmitter. Identify a suitable main socket. If a switch is fitted to the socket, switch off. Plug  in the LPC to  the mains socket  and then switch back  on. Set the  LPC rotary switch to match the two indicator lights. Set the transmitter to the frequency to be located.(8 kHz or 32 kHz are good frequencies for this application). Set the output to mid range.

Check the  batteries in  the Transmitter and Receiver. Replace/recharge if necessary. Turn the instruments off. 2.  Ensure all conductors are de-energized 3.  Lift Grounds. Lift Grounds (of all conductors in the circuit) at both ends of the faulted cable section.   WARNING When the Transmitter is set to FF Low/High , the external OUTPUT JACKS produce High Voltage. Do not touch these jacks, electrical shock will result!  Attach Transmitter to Conductor Check Fault Resistance 1.  Turn Transmitter OFF. 2.  Plug the connection leads into the Transmitter. 3.  Stretch Black-lead 180 degrees away from conductor. 4.  Push grounding rod into earth and clamp black lead to grounding rod. Establish the best ground possible.   5.  Clamp Red lead to target conductor sheath.   6. Turn Transmitter on 7.  Press the Frequency button (f) to select FF Low or FF high. Note: Press the up arrow button to increase current or switch to FF High for long distance cables or pipes or when the resistance is high.
8  Using the vLoc-9800 Page 46 of 50   Use the vLoc-9800 Receiver to Trace the Pipe or Cable 1.  Trace and mark the cable as you proceed towards the fault.   2.  Place the A-frame  in the ground with the red facing the transmitter and the green facing the receiver. 3.  Hold the A-Frame so the spike with the red band is about 2 steps away from the ground rod and the spike with the green band is in-line with the targeted cable. The A-frame  must be placed as shown in figure 3-5. Push the A-Frame spikes into the ground.     4.  Plug  in  the  A-frame  to  the  receiver  accessory  socket.  When  the  receiver  is  switched  on,  it  will automatically default to the A-frame screen Switch the Receiver “ON” wait until arrow flashes    The A-frame accessory is used to detect ground faults on pipes and cables. In the case of pipes, the faults consist of coating defects. In the case of cables, faults are usually caused by insulation damage allowing the metallic sheath (or internal conductor) to become in contact with the ground.  To detect a damaged section, the line should be isolated and have all ground  bonding removed. This will ensure that the ground fault is not masked by deliberate bonding to ground. The A-frame cannot distinguish between these two situations.
8  Using the vLoc-9800 Page 47 of 50   After  isolating  the  line,  use  the  vLoc-9800  transmitter  resistance  measuring  function,  or  a  dedicated resistance measuring device to confirm that there is a fault to ground. The A-frame will typically detect faults up to 2 mega ohm and above (depending on the distance from transmitter, soil conditions etc).  Connect the transmitter to the target line using the red lead. A  ground stake needs to be pushed into the ground and the black cable clipped to it. Try to place the earth stake as far as possible from the line to be evaluated. This ensures return currents do NOT distort the results. Switch on the transmitter and select either FF low or FF high. Use FF high if the line to be surveyed is long or the fault resistance is high.    Image for reference only and may differ from actual image  Remove the plastic spike covers from the A-frame. Walk along the route of the line placing the spikes of the A-frame in the ground (with the green leg pointing away from the transmitter connection point) every two or three paces. If starting near the transmitter, the green Arrow on the display will point away from the ground point. As the distance from the transmitter increases, the dBuV reading will reduce and eventually the green and red arrow will fluctuate or disappear altogether. This is because the fault location is further along the line. The pipe and cable can still be located by pressing the “M” pushbutton to go to peak mode line locating mode.    This allows the user to confirm the position of the target line. Press the “M” pushbutton again to re-enter the
8  Using the vLoc-9800 Page 48 of 50 A-frame mode.      Eventually the A-frame will  detect the fault signal and the  “Fault Find” arrow will point  forwards. Continue moving forwards, it may be worth reducing the distance between measurements points as the fault is neared. The dBuV reading will increase as the fault is neared. Maximum reading will be just before and just after the fault. When over the fault, the dBuV reading will drop and the arrow will flip backwards indicating that the position of the fault has been passed. Carefully place the A-frame before and after the fault to pinpoint the position. Repeating this across the line direction will pinpoint the fault laterally. The fault will be at the point where the lateral fault is identified.    WARNING Always disconnect or isolate cables before making connections to conductors. Never  attach  the  transmitter  to  live  cables  unless  authorised.  Use  the appropriate accessories.  TIP If it is suspected that there is just one fault. Insert the A-frame approximately one meter from the earth stake. Note the dBuV, this is approximately the maximum dBuV reading that will be measured over the fault.        8.4.3  Using the Remote Antenna USB
8  Using the vLoc-9800 Page 49 of 50   The remote stethoscope antenna can be used to help identify a particular cable on a cable tray or where cables are bunched together.  Methods: 1.  Connect  a  signal  to  the  cable  to  be  identified.  The  remote  stethoscope  functions  has  an  operational frequency range of 512Hz up to 200 kHz, but low frequencies should be a preference in this application as they are less likely to leak or bleed over to other cables. 2.  The best method of signal application when identifying cables is to use the signal clamp. This is because the signal clamp applies a signal to the target cable and shares an equal amount with other cross bonded cables.   3.  When using the signal clamp, both ends of the target cable should be grounded. Apply the clamp below the ground point. Applying the clamp above the ground point will prevent the signal finding the return path through the ground, so is not advised.   4.  If this is not possible use a transmitter signal clamp and you have confirmation that the cable is out of service, use a direct connection lead to make an electrical connection to the cable. Removing any cross bonding between cables prevents the signal travelling along commonly bonded cables.    5.  Do NOT use the Induction method as the signal will appear on all cables in the area of the transmitter. 6.  Connect the remote stethoscope antenna to  the accessory input of the Receiver. The correct settings and user interface will be automatically selected.
8  Using the vLoc-9800 Page 50 of 50  7.  Ensure the frequency selected on the vLoc is the same as selected on the transmitter. 8.  Place the stethoscope on each of the suspected target cables with the flats of the antenna in line with the route of the cable.  9.  Note the dB reading of each cable. The one with the largest reading is likely to be the target cable. 10. If necessary adjust the sensitivity of the vLoc so that the signal is within the operating section of the bar graph. This will help identify the cable if the signal levels are similar because of cross coupling of the signal.   WARNING The  remote  stethoscope  antenna  is  a  useful  tool  to  help  identify  cables. However,  it  should  not  be  used  as  positive  identification  before  an  unused cable  is  cut.  Always  follow  company  procedures  when  cutting  disused  or isolated cables.  TIP The remote antenna USB stethoscope can be used to help identify disused and isolated cables. This process can be further enhanced if the cable is isolated and is of a twisted cable construction.  Method: 1.  Connect  the  transmitter  to  two  of  the  cores  of  the  cable.  At  the  far  end  short  together  these  two conductors making a loop. 2.  Set the transmitter to a low frequency such as 640Hz and set the output to maximum.   3.  At  the  point  of  interest,  run  the  remote  stethoscope  antenna  along  the  suspected  target  cable. If  the correct cable is being assessed the signal will increase and decrease in sympathy with the twist of the two conductors within the cable. 4.  If the signal is a steady level and does not rise and fall, this is probably NOT the target cable.   WARNING The  remote  stethoscope  antenna  is  a  useful  tool  to  help  identify  cables. However, it should not be used as positive identification before an unused cable is  cut.  Always  follow  company  procedures  when  cutting  disused  or  isolated cables.

10  Glossary Page 55 of 50 Glossary      Active Locate  A locate where a transmitter is used to apply a signal to a buried pipe or cable, the position of which is then located by a receiver tuned to the same frequency.  Active Signal  A signa l applied by the locator transmitter to a buried line. Typical this is a very precise frequency.  Attenuation  The reduction of an electromagnetic signal from a pipe or cable.  Clamp (or Coupler)  An accessory used to apply the transmitter signal to an insulated line, removing the  need  to  connect  the  transmitter  signal  directly  to  a  conductor  or  cable sheath.  Compass  Line  direction  indicator  (although  visually  like  a  compass,  this  is  the  only relation to a compass.)  Coupling  The act of signals transferring to lines to which they were not originally applied. Coupling can be “direct” where the target line has an electrical connection to another  line,  or  “induced”  where  the  signal  radiates  from  the  target  line  to another line or lines.  Display  The information visually available on the dot matrix display.  Line  A generic term for any buried pipe or cable.  Null  A minimum response to a buried line.  Passive Locate  A locate where the receiver searches for a wide range of signals that radiate from buried pipes or cables. These signals come from a variety of sources in the environment and couple to the buried (& overhead) lines. Typical examples 50 / 60Hz and LF/VLF radio.  Passive signals  A  wide  range  of  signales  that  radiate  from  buried  pipes  or  cables.  These signals come from a variety of sources in the environment and couple to the buried (& overhead) lines. Typical examples 50/60Hz and LF/VLF radio.  Peak  A maximum response to a buried line.  Pinpoint  Using a receiver to identify the exact position of a buried line.  Response  The  indication  that  the  receiver  gives  which  is  caused  by  the  signals  it  is receiving.  This  can  be  visual,  audio  or  both.  Typically  it  is  displayed  on  the locators  dot  matrix  display  and  audibly  from  a  loudspeaker  in  the  receiver housing.  Search (sweep)  This describes the act of looking for a buried line within a given area.  Sonde  A  small transmitting coil  which may  be  built into  a  product such  as a  sewer camera or packaged as a small self contained battery powered transmitter. A receiver tuned to the same frequency can locate the position of the Sonde and
