Three-phase Power Meter Calibration Device is suitable for industrial and mining enterprises and electricity meter manufacturers to quickly and in small batches test various single and three-phase electricity meters. It can simultaneously output high stable and accurate parameters such as three-phase voltage, current, and phase, and can also independently adjust phase separation to increase output flexibility.

Multi-functional Electric Instrument Calibration Device is a high-precision instrument with three-phase AC and DC output and measurement. The instrument applies three-phase synchronization technology, broadband amplifier technology, digital-analog double closed-loop technology and other advanced technologies to output high-precision three-phase AC and DC voltages, currents, phases, harmonics, power and electrical energy, which is suitable for testing or calibrating all kinds of voltmeter, ammeter, power meter, power factor meter, phasor meter, synchronization meter, power meter and other calibration devices
