Three-phase energy meter field calibrator
3. Methods of Use of Functions
3.1 Calibration information settings
Constant:
This is to set the energy constant of the energy meters measured and the constant
ranges from 1 to 99999; it supports from ordinary mechanical single-phase energy meters
to the latest three-phase electronic energy meters, and the constant unit is Plus/kW.h
For instance: when the meter constant is 600Plus/kW.h

number.
N (number of sampling turns):
Number of turns: each the photoelectric sampler receives a pulse or black pointer of
the energy meter, the photoelectric sampler will produce a pulse, and the number of turns is
the error calculated after the instrument receives how many pulses.
For example: the black pointer of the energy meter turns 2 circles, the instrument
