3) Comparing LED Pulses with Substandard Meter Pulses
This method may be used where the test equipment has the facility to calculate meter errors based on the pulse output
from a substandard meter. It will be necessary to set the pulse value of the meter under test (shown on the meter
nameplate) into the meter test equipment.
The duration of each test must be at least 60 seconds
The number of LED pulses should be greater than:-
Itest = Test current
V = System voltage
PF = Power factor of test load
K = LED pulse value, impulses/kWh
