Verifying accuracy test

The following are guidelines for testing the meter; your meter shop may have specific testing methods.

DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH

•Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E in the USA or applicable local standards.

•Turn off all power supplying this device before working on it.

•Always use a properly rated voltage sensing device to confirm that all power is off.

•Do not exceed the device’s ratings for maximum limits.

•Verify the device’s power source meets the specifications for your device’s power supply.

Failure to follow these instructions will result in death or serious injury.

1.Turn off power to all test equipment. Use a properly rated voltage sensing device to confirm power is off.

2.Connect the test voltage and current source to the reference device or energy standard. Ensure all voltage inputs to the meter under test are connected in parallel and all currents inputs are connected in series.

3.Connect the control equipment used for counting the standard output pulses using one of these methods:

Alarm / energy LED

Align the red light sensor on the standard test bench armature over the front

panel alarm / energy LED.

 

 

 

Digital output

Connect the meter’s digital output to the standard test bench pulse counting

connections.

 

NOTE: When selecting which method to use, be aware that the Alarm / energy LED and digital outputs have different pulse rate limits. See “Energy pulsing considerations” on page 97 for details.

4.Before performing the verification test, let the test equipment power up the meter and apply voltage for at least 30 seconds. This helps stabilize the internal circuitry of the meter.

5.Set the meter’s power system to 3PH4W Wye Gnd (3-phase, 4 wire Wye with ground).
