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. Type-Meter type 11. Date of manufacture 7 Ross Cannon Street - York, SC 29745 - Phone (803) 628-0035 - Fax (803) 628-0282 - info@visionmetering.com – www.visionmetering.com Vision Meter Operating Manual Singlephase & Network Vision Metering LCD Display The Vision meter LCD display consists of a 6 digit alphanumeric display along with numerous fixed data displays for indication of the many energy values and conditions the Vision meter may encounter.

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% (noncondensing) 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 7 Ross Cannon Street - York, SC 29745 - Phone (803) 628-0035 - Fax (803) 628-0282 - info@visionmetering.com – www.visionmetering.com Vision Meter Operating Manual Singlephase & Network Vision Metering 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 K T. 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. 7 Ross Cannon Street - York, SC 29745 - Phone (803) 628-0035 - Fax (803) 628-0282 - info@visionmetering.com – www.visionmetering.com 8 Vision Meter Operating Manual Singlephase & Network Vision Metering 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 7 Ross Cannon Street - York, SC 29745 - Phone (803) 628-0035 - Fax (803) 628-0282 - info@visionmetering.com – www.visionmetering.com Vision Meter Operating Manual Singlephase & Network Vision Metering Common Site Configurations 7 Ross Cannon Street - York, SC 29745 - Phone (803) 628-0035 - Fax (803) 628-0282 - info@visionmetering.com – www.visionmetering.com 10 Vision Meter Operating Manual Singlephase & Network Vision Metering 7 Ross Cannon Street - York, SC 29745 - Phone (803) 628-0035 - Fax (803) 628-0282 - info@visionmetering.com – www.visionmetering.com Vision Meter Operating Manual Singlephase & Network Vision Metering 7 Ross Cannon Street - York, SC 29745 - Phone (803) 628-0035 - Fax (803) 628-0282 - info@visionmetering.com – www.visionmetering.com 12 Vision Meter Operating Manual Singlephase & Network Vision Metering 7 Ross Cannon Street - York, SC 29745 - Phone (803) 628-0035 - Fax (803) 628-0282 - info@visionmetering.com – www.visionmetering.com Vision Meter Operating Manual Singlephase & Network Vision Metering 7 Ross Cannon Street - York, SC 29745 - Phone (803) 628-0035 - Fax (803) 628-0282 - info@visionmetering.com – www.visionmetering.com 14 Vision Meter Operating Manual Singlephase & Network Vision Metering 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.
