The single-phase energy meter calibrator is a set of 0.1-magnitude high precision field calibration instrument, but it is qualitatively different from the single-phase field calibration made of energy meter chip. Where there is no load on the spot,its current output can be used as a virtual load, which is greatly convenient for field testing of single-phase energy meter.
