The Vision  singlephase  meter  family  offers  metering  solutions  for  all  singlephase  metering configurations encountered in normal utility environments.   Meter Characteristics The Vision meter is comprised of a base assembly, bezel and cover.  The base assembly contains the current transformer(s) which are used for current sensing along with the current carrying bus bars and voltage connections.  The meter bezel houses the circuit board containing the metering chipset,  RF  communications  and  LCD  display.    The  standard  meter  cover  is  a  UV  stabilized polycarbonate cover with opticom connection.  Glass covers are also available upon request.  The Vision meter is designed to operate continuously in a temperature range of  -40C to  +85C with a relative humidity of 5% to 95% (non-condensing).   The Vision meter is rated as an ANSI C12.20 accuracy class 0.5 meter.  Typical accuracy results will fall within +/- 0.2% for singlephase Vision meters. Nameplate Information The Vision Meter nameplate can be customized to each utility’s labeling specifications.  Some  information  is  standard  on  all  meter  nameplate  templates.    Typical  meter nameplate information includes:   1. Utility name area 2. Utility company number barcode 3. Voltage-Rated operating voltage 4. Meter Class-Full load current rating 5. Form-Meter service form 6. Kh-Watthours per disk revolution (not used in Vision meter disk emulator) 7. Kt-Watthours per test pulse 8. TA-Full load test amps 9. Vision Metering serial number 10.

Available forms include:  Type Form Voltage Class Kh TA V1S 1S 120V 100 1.0 15 V2S 2S 240V 200 1.0 30 V2S 2S 240V 320 1.0 50 V2SD 2S 120-480V 200 10.0 30 V3S 3S 240V 20 1.0 2.5 V3SD 3S 120-480V 20 1.0 2.5 V4S 4S 240V 20 1.0 2.5 V4SD 4S 120-480V 20 1.0 2.5 V12S 12S 120V 200 1.0 30 V12S 12S 120V 320 1.0 50 V12SD 12S 120-480V 200 10.0 30 Operating Parameters The  Vision  meter  is  fully  compliant  with  ANSI  C12.1,  C12.10  and  C12.20.    Operating parameters for the Vision meter are as follows: 1. Temperature-Operates  in  temperatures  between  -40C  to  +85C  within  the accuracy  limits  of  ANSI  C12.1  and  C12.20.    The  LCD  display  will  not  function below -25C but meter operation is unaffected and LCD operation resumes once temperature goes above -25C. 2. Humidity-Operates  normally  within  a  humidity  range  of  5  to  95%  (non-condensing) 3. Voltage- Operating voltage for the Vision meter is nameplate voltage +/- 20%.  For example, a 240V meter will operate normally from 192V to 288V. 4. Frequency-Vision meters operate normally at a rated frequency of 60Hz +/-5% 5. Maximum current-Maximum allowable current is annotated by the Class rating on the meter nameplate. Standard Operation The Vision meter ships pre-programmed from the factory ready for installation.  Meter settings and configuration can be modified after shipment using the Vision 20/20 software program.  No initial programming is required to begin using the meter under normal circumstances.  When power is applied to the Vision meter, the startup sequence will commence.  The LCD will indicate the firmware version of the meter for approximately 3 seconds.  This firmware version should be noted when modifying settings using our Vision 20/20 software because previous

In order to ensure full  functionality,  please  match  software  and  firmware  version  when  modifying  meter configuration. Energy Registration The  Vision  meter  can  be  configured  to  display  kWH  consumption  in  a  number  of different manners.  The options for kWH accumulation are: 1. kWH  Delivered  (Unidirectional)  -  Energy  is  only  accumulated  in  the  forward direction only.  If current flow is reversed through the meter, the kWH value still increments in the forward direction.  This is the default setting and most secure configuration. 2. kWH Delivered – Energy is only accumulated in the forward direction.  Reverse current flow is not included in the display.  This option is enabled by selecting “Reverse  Allowed”  in  the  Vision  20/20  software  and  only  displaying  kWH delivered. 3. kWH  Received-Reverse  current  is  accumulated  and  displayed  as  a  separate register. 4. kWH Net-Meter displays kWH Delivered minus kWH Received Instantaneous Demand The Vision meter can be configured to display Instantaneous Demand in the center of the bottom row of the  LCD display.  This is a real time kW indication that is updated once  per  second.    This  display  auto  ranges  from  0  to  3  decimals  depending  on  the magnitude of the instantaneous demand value.   Calibration/Accuracy testing Vision meters are calibrated to +/-0.2% prior to shipment therefore no user calibration is  required.    Accuracy  testing  can  be  accomplished  using  standard  watthour  test equipment which utilizes LED pickups.    Watthours  per  pulse  output  from  the  LED  is  shown  on  the  meter  nameplate  as  KT.  Meters  may  have  both  a  KT  and  a  Kh  value  in  some  cases.    When  only  one  value  is present,  KT  and  Kh  are  equivalent.    Full  load  accuracy  testing  is  performed  at  the nameplate test amps (TA).  Light load testing is performed at 1/10 the full load value.  Once the test board is set up using the nameplate parameters, the meter can be tested by  following  the  manufacturer’s  recommended  test  procedure.    The  Vision  meter should never require calibration after initial factory calibration.

The wiring diagrams contained within this manual are not intended to replace utility guidelines or installation  guides.    These  diagrams  are  provided to  assist  in  determining the proper service type only.  The Vision meter is designed to  be  inserted  into a standard ANSI style meter  socket.  Forms 1S, 2S and 12S meters are self-contained meters which are rated to pass full load current  through  the  meter.    Forms  3S  and  4S  meters  are  transformer  rated  devices which are only rated to pass current flow from the secondary of a current transformer through the meter.  When  inserting  a  meter  into  an  ANSI  socket  care  should  be  taken  to  examine  the socket jaws to ensure that proper  tension  is present in  the  meter  jaws to avoid high resistance connections when the meter is inserted.  High resistance connections in the meter  jaws  can  lead  to  increased  temperatures  within  the  socket  and  may  lead  to shortened meter life expectancy.  Once the  meter is inserted into  the  meter  socket and power is  applied the following sequence occurs: 1. Meter firmware version is displayed for approximately 3 seconds 2. LCD segment check is displayed for 8 seconds 3. Normal scrolling of programmed display parameters commences
