Verifying accuracy
Verifying accuracy test
The following tests are guidelines for accuracy testing your meter; your meter
shop may have specific testing methods.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Failure to follow these instructions will result in death or serious injury.
• Apply appropriate personal protective equipment (PPE) and follow safe
electrical work practices. See NFPA 70E in the USA, CSA Z462 or
applicable local standards.
• Turn off all power supplying this device and the equipment in which it is
installed before working on the device or equipment.
• 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.
1. Turn off all power supplying this device and the equipment in which it is
installed before working on the device or equipment.
2. Use a properly rated voltage sensing device to confirm that all power is off.
3. 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 current inputs are connected in series.
A Reference device or energy standard
B Test voltage and current source
C Meter under test
4. Connect the control equipment used for counting the standard output pulses
using one of these methods:
Option Description
Energy pulsing LED Align the red light sensor on the standard test bench armature over
the energy pulsing LED.
Onboard Digital
output Connect the meter’s onboard digital output to the standard test bench
pulse counting connections.
NOTE: When selecting which method to use, be aware that energy
pulsing LEDs and digital outputs have different pulse rate limits.
