The multifunctional watt-hour meter field calibrator is a full-featured, high-accuracy electric energy meter field effect device and a comprehensive electrical parameter measurement device. The device is controlled by a single-chip microcomputer and incorporates the latest digital signal processing technology to provide a complete test function for on-site calibration power meters and other various electrical instruments. This field calibrator is also suitable for precise testing of laboratory AC parameters. A variety of electrical instrument verification, and can be used as a standard part of a sophisticated power meter calibration device. In the case of continuous power, without removing the meter, on-site detection of the speed of the three-phase power meter that is the error of the meter; is the necessary equipment for the majority of the electricity measurement department, power supply and electric power inspection department.
