GF112V2 Handheld Single Phase Energy Meter Calibrator

calibration of energy meter

GF112V2 is a single phase handheld energy meter accuracy test set in class 0.1, used for testing all kinds of single phase electronic meters error on site. Wide measurement range from 1mA to 120A and 0 to 600V, frequency range 40.000Hz to 70.000Hz, and also can be used to test alternating current electrical parameters - voltage, current, active power, reactive power, apparent power, harmonics, phase angle, power factor, frequency, energy etc. It can display U & I wave form and vector diagram. Small size, light weight, simple and convenient operation. It is an ideal testing tool for the metrology departments of electricity power companies.
