Vision Metering
Product Description
Vision Metering’s Vision meter family is a solid state watt-hour meter line designed to provide
flexible and reliable metering solutions for all residential and commercial applications. 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

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

software versions may not be compatible with later firmware configurations. 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.

Meter Installation
Meter installation should only be performed by a trained meter technician. 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

Meter Self-diagnostics
The Vision Meter runs self diagnostics upon startup and every 3 minutes during normal
operation. There are two error indications that are displayed on the LCD display.
1. Wiring fault - The service disconnect indicator will flash every one second if a
wiring fault is detected based on expected voltage and current configuration by
meter form.
2. EEPROM Error – The “Err” indicator will illuminate on the bottom left corner of
the LCD display if the Vision meter detects a problem writing data to the
EEPROM during normal operation.
