Product Description

CN8902 Three-phase electrical parameter measuring instrument

The three-phase electrical parameter tester is suitable for the true RMS detection of three-phase voltage, current, power, power factor, frequency and other parameters in motors, pumps, transformers, electric power and other industries, and can be wired according to two wiring modes of three-phase three-wire system and three-phase four-wire system, and can also be used as a single-phase meter. The accuracy is 0.5 and 0.2 grades.
Tester measurement range and accuracy:
