Verifying accuracy 9810 series - User manual
285 7EN05-0390-08
A Reference device or energy standard
B Test voltage and current source
C Meter under test
2. 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.
3. 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.
4. Configure your meter power settings (such as voltage, current and frequency) to align with
the reference device.
5. Depending on the method selected for counting the energy pulses, configure the meter’s
energy pulsing LED or one of the digital outputs to perform energy pulsing. Set the meter’s
energy pulse constant so it is in sync with the reference test equipment.
6. Perform accuracy verification on the test points. Run each test point for at least 30 seconds
to allow the test bench equipment to read an adequate number of pulses. Allow 10 seconds
of dwell time between test points.
