Features:
 

1. The instrument is a high precision measuring instrument, which can be used for electric energy meter calibration, electric parameter test and the detection of the power quality problems such as wave distortion, voltage fluctuation, three-phase unbalance
2. Can on line test the integrated error of the real load testing and metering equipment, without power off, without changing the metering circuit; without opening the metering device
3. It can accurately measure a variety of electrical parameters, such as voltage, current, active power, reactive power, phase angle, power factor, frequency,etc.
4. It can display the vector diagram of the measured voltage and current, by which users can judge if the metering device wiring is correct or not. And can discriminate 48 kinds of wire connection under three phases three wire connecting mode, and can auto calculate electric quantity compensation
5. The current circuit can be measured
6. Can check voltage meter, current meter, power meter, phase meter and other indicators as well as three-phase three wire, three-phase four wire, single phase 1A, 5A all kinds of active and reactive power meter.
7. Can use photoelectric, manual, pulse and other methods for energy meter calibration
8. Measurement and analysis of the AC power quality from the to client can be easily done, including frequency deviation, voltage deviation, voltage fluctuations, flicker, three-phase voltage unbalance factor and harmonic.
9. It can display single-phase voltage, current waveform and can display three-phase voltage and current waveform at the same time.
