Three-phase energy meter field calibrator
Calibration method for basic error of the calibrator:
Calibration signal is from the low-frequency output signal of standard energy meter and is
input from the signal (FI1 or FI2 level signal) end of the photoelectric head interface on the
calibrator panel.
As shown below
The standard meter is used as calibration meter. The calibration method of the calibrator is
automatic (photoelectric) mode.
