22Set-upPress 1(Correlate on start-up) Toggles between YES and NO. If set to YES, the control unitwill go straight to the correlate screen after turning on. If set to NO, the control unit will gostraight to the Main Menu after turning on.Press 2(Default filters) Toggles between CLEAR and RETAIN. If set to CLEAR, in surveymode, the filters will clear each time a new correlation is processed. If set to RETAIN, insurvey mode, the filters will retain a set filter setting (set by the user) for every correlationprocessed.Press 3(Survey mode range) Toggles between 0.8, 2.4 and 4.0 seconds. Each of thesevalues provides the time delay range over which the correlator will correlate, where the timesin seconds shows twice the range. For example, over longer distances the 4.0 second rangeshould be used to give +2 seconds to –2 seconds. If entering pipe data, the survey moderange automatically defaults to the appropriate setting.Press 4(Correlation sensors) Toggles between the pairs of sensors to be used. Red-Blue,Red-Yellow, Blue-Yellow, Base-Red, Base-Blue and Base-Yellow.Press 5(Radio Mode) Toggles between HIGH power and LOW power.

27Correlation ScreenA dashed cursor line shows the position of the largest peak (best result). The dashed cursorline can be moved once the correlation has been stopped, by using the arrow keys. Movingthe dashed cursor line alters the correlation distance.This screen shows the result of a correlation where the position of the leak is. In this example63.4 metres from the Red Out Station and 60.6 metres from the Blue Out Station. The time delay is calculated at 2.3 milliseconds.The correlation shown has a SNR of 29:1. Signal to Noise Ratio (SNR) means the largestcorrelation peak is 29x larger than any other displayed peak shown on the correlation graph.Hence the larger the SNR the more pronounced the peak will be.Press 1(Listen) Attach the headphones to the control unit before pressing 1. Use the arrowkeys to select the sensor required to listen to; BASE, RED, BLUE or YELLOW. The sound willtransmit in blocks of approx 20 seconds. To stop listening press ENTER, but note the soundwill continue until the 20 seconds elapses.
28Pipe dataPress 2(Pipe data) To accurately locate a leak position the user must enter the correct information with respect tothe physical properties of the pipe. Each section must be entered to be accepted by thesystem.Press 5 to Add new pipe data.A default setting appears.
29Press 1 to enter Length, the distance between the sensors. In this example 124m.Press 2 to enter material type, use the arrow keys to select the required pipe material andpress ENTER. In this example cast iron is selected.
30Press 3 to enter the diameter of the pipe. In this example 80mm. The velocity column will thenautomatically be updated. In this example 1.280 m/ms.To add another pipe length for mixed material situations, press 5 to add another pipe. Ifworking on mixed materials, work from the sensor colour displayed at the bottom of the pipedata screen, back to the sensor colour at the top of the screen. Up to 6 mixed materials canbe used in one correlation. In this example, from the blue sensor the cast iron pipe wasentered first, the ductile iron pipe was second and the PVC pipe was third.
31To delete a pipe, use the arrow keys to highlight the relevant pipe to remove and press 6. To delete all pipe data press 0.To use a manual velocity the user has calculated, press 4 and type in the new velocity value,this will automatically update the default value for the current correlation only.To enter and store extra user defined velocity’s and diameters, press 2 Materials, then press1 Edit materials, then press 1 Edit table, then press 3 Add entry. To restore to factory setvalues see Test and Service menu.
32Zoom Press 5 (Zoom) To see a more enhanced view of the leak centred around the dashed cursorline. Moving the dashed cursor line along the graph to the required point then press 5.Use the arrow keys to zoom in or out stage by stage.For a quicker zoom press 1 to zoom to maximum view or press 5 to zoom to a minimum view.
33Peak Suppression ScreenPress 6(Peak Suppression) To suppress a section of the time delay range from the currentcorrelation. This may be used to remove known leaks or demand usage that may be hidingunknown leaks.Move the dashed cursor line to the start point of the data to be removed and press 1 to selecta start point. A small arrow will appear below the correlation graph. Move the dashed cursorline along the data to select the stop point. Press 1 again and the section of the data to besuppressed will disappear from the correlation graph as shown below.Press Enter to accept the data and a new correlation can be carried out without thesuppressed data. To replace the removed data press 2 delete.
34View SettingsPress 7 (View Settings) During correlation or after stopping a correlation press 7 to view allpipe data and filter settings currently in use. A pop up box appears to display the information.Press Cancel to remove the display.
35Calculate VelocityPress 8(Calc Vel) After stopping correlating the option to calculate velocity appears. Avelocity check gives a more accurate velocity of the pipe to be correlated instead of using thedefault velocity value.To calculate velocity a leak must be present, either real or induced. The leak can either bebetween the sensors called an “In Bracket” check or outside of the sensors called an “Out ofBracket” check. Unlike correlation, where the more central the leak is positioned between thesensors, the more accurate the result. A velocity check requires the leak to be positionedcloser to one of the sensors to create a larger time delay.The procedure for a velocity check is to position your sensors as described above. Induceyour leak or use the real leak. Correlate as normal entering the correct pipe data. After a goodcorrelation peak, stop correlating and press 8(Calc vel). The screen below will be displayed.Enter the position of the leak from the RED Out Station.If the leak is “In Bracket” between the sensors, then enter the distance from the leak to theRED sensor. (In this example 92.7m)If the leak is “Out of Bracket” to the left of the RED sensor, then enter the distance 0If the leak is “Out of Bracket” to the right of the second sensor, then enter the distancebetween the RED sensor and second sensor.
36A new velocity will be displayed under the correlation graphThe control unit then gives you the option to either use the calculated velocity by pressingENTER or CANCEL to ignore it.By accepting the calculated velocity value, the default velocity value under Pipe Data will bereplaced with the new calculated velocity value. A new correlation position may now bedisplayed using the more accurate velocity value.
37FiltersIf correlating with pipe data entered, the default filter settings will be used depending on theproperties of the pipe. Some times this may not be accurate enough to filter out unwantedfrequencies, so the user may wish to alter the filer settings to remove certain frequencies thatare influencing the current correlation.Press 3 (Change Filters) Displays a pox up box with four options :-Quick set-metallicQuick set-non metallicClear allManual settingsBy using the arrow keys highlight the required option and press ENTERQuick set-metallic removes all frequencies from 0Hz to 405Hz. So the sensors will onlylisten to frequencies of 406Hz and above.Quick set-non metallic removes all frequencies from 696Hz and above. So the sensors willonly listen to frequencies of 695Hz and below.Clear all removes any filter settings set and will listen to all frequencies.Manual settings allow the user to view the frequencies and set to the user preference.The filter screen displays the frequencies heard at the two sensors in use. The bottom axis ofeach graph displays the frequency level starting at 0Hz to the left. Two cursor lines aredisplayed on each graph and are move by using the arrow keys. The longer dashed cursorline is the current line selected to move. The lines on each graph will not cross. The positionof the current cursor line is displayed under the second graph, in this example 275Hz.
38Press 1 (Select cursor) This toggles between the two cursor lines. Only the longer dashedcursor line can be moved.Press 2 (Low cut-off) When the left cursor line has be selected the low cut off option isdisplayed. Move the left cursor to the required position and press 2. This will remove allfrequencies to the left of the cursor line. Removed frequencies are displayed in a cyan colour.In this example the cursor was moved to 257Hz and a low cut off was selected, so allfrequencies from 0Hz to 257Hz will be removed.Press 2 (High cut-off) When the right cursor line is selected the high cut off option isdisplayed. Move the right cursor to the required position and press 2. This will remove allfrequencies to the right of the cursor line. Removed frequencies are displayed in a cyancolour. In this example the cursor was moved to 505Hz and high cut off was selected, so allfrequencies from 505Hz and above will be removed. By pressing ENTER to accept the datawould mean frequencies between 258Hz and 504Hz only are being used to process thecurrent correlation.
39Press 3 (Notch) This options allows a “notch” of frequencys to be filtered out. Move theselected cursor to the left of the area of frequency to be removed and press 3. A small arrowappears under the graph. In this example 81Hz is selected.Move the same cursor to the right of the area to be removed and press 3 again. In thisexample 105Hz. The notch area of filtered out frequencys will change colour to cyan. Thecurrent correlation will now ignore frequencys from 81Hz to 105Hz but will use all otherfrequencys.Press 4 (Clear all) This clears all filter settings currently set.Press 5 (Auto Filter off) This will toggle between Auto Filter OFF and Auto Filter ON. Atpresent this option is under development and will be released on a future upgrade.
40Program upgrade (Software and Firmware)The MicroCorr Digital correlator and Out Stations have been designed so that their programscan be upgraded as the latest developments take place.The MicroCorr Digital Software is defined as the user interface within the base station, andthe Firmware describes the program that communicates between the correlator base stationand the Out Stations.To upgrade the Software and/or Firmware a program must be installed on the PC. This is theMCD Updater Application. The base unit requires both software and firmware to operate,where as the Out Stations only require firmware to operate.The application, the latest software and the latest firmware are all available as downloadsfrom the Palmer website www.palmer.co.uk/microcorr.htmOnce all the files have been downloaded to the PC start the MCD Updater Application andfollow the instructions as described below.Screen descriptionThe fields of the MCD Updater screen are described by number below.Current System Information1. This field gives the boot sector version within a base/out station and cannot be changedby the user. It can only be used by Palmer engineers for system diagnostics.2. This field gives the current firmware version within a base/out station.3.

In this menu there are 4 predefined options COM1 through COM4, and a userdefined port which allows the user to specify the port to use.Important Notes for upgrading a MicroCorr Digital correlator (August 2003)When using the upgrade program for the MCD the following points should be noted:All of the correlation (.ked) files stored on the MicroCorr Digital will be deleted during theupgrade operation. Therefore the user must save any required correlation files to a PCbefore upgrading the software.Once the upgrade procedure starts the power to the PC and the MCD should not beinterrupted, if it is the MCD will be rendered unusable.1. Reboot your PC before starting, and ensure the Palmer Upgrade program is the onlyapplication running, this ensures no other application can cause a break in the upgradeprocedure.2. Ensure the MCD is connected to a charger that is switched on. This ensures a low batterydoes not cause a shutdown.3. Never try to interrupt the upgrade procedure once it is initiated.
42Upgrading a Base StationThe following steps should be followed to upgrade the software/firmware within a basestation:1. Connect the PC to the base station via the supplied serial cable.2. Connect external power to the system. This ensures that the system does not powerdown while the upgrade is in progress. Then back up all correlation files to the PC.3. Start the MCDUpdater application and ensure that the ‘port’ is set correctly and ‘unit type’is set to base.4. Click on the ‘Update’ button to retrieve the current versions from the system.5. Click on the ‘Browse Firmware’ and ‘Browse Software’ buttons and locate the firmwareand software update files. If only the software or the firmware is to be upgraded then onlyselect the required upgrade file.6. Ensure that the update files are newer than those currently installed on the system. (Thelatest version should always be used unless told specifically by your Palmerrepresentative that an older version should be used).7. Click on the ‘Program’ button and wait for the operation to complete.8. Remove the power and reset the system. Wait for the system to fully restart, then click onthe ‘Update’ button and verify that the software/firmware has updated successfully.9. Switch the unit off completely and then switch back on again.Upgrading an Out StationThe following steps should be followed to upgrade the firmware within an out station:1. Connect the PC to the out station via the supplied serial cable.2. Connect external power to the system. This ensures that the system does not powerdown while the upgrade is in progress.3. Start the MCD Updater application and ensure that the ‘port’ is set correctly and ‘unit type’is set to Out Station.4. Click on the ‘Update’ button to retrieve the current versions from the system.5. Click on the ‘Browse Firmware’ button and locate the firmware update file.6. Ensure that the update file is newer than that currently installed on the system. (The latestversion should always be used unless told specifically by your Palmer representative thatan older version should be used).7. Click on the ‘Program’ button and wait for the operation to complete.8. Remove the power and reset the system. Wait for the system to fully restart, then click onthe ‘Update’ button and verify that the firmware has updated successfully.9.
