  • Calibrate three phase, single phase, active or reactive meter error;
  • Measure U(voltage) of three phase or single phase;
  • Measure I(current) of three phase or single phase;
  • Measure active power of three phase or single phase;
  • Measure reactive power of three phase or single phase;
  • Measure apparent power of three phase or single phase;
  • Measure power factor of three phase or single phase;
  • Measure phase angle between voltage and current;
  • Measure frequency of power line;
  • Display vector diagram;
  • Display waveform of U and I;
  • Analyze and display content of harmonic of U and I;
  • Store and display measured data;
  • Optional 5A, 20A, 100A, 500A, 1000A, 2000A, 3000A current clamp;
  • Measure CT variable ratio;
  • Measure the ratio or lag-angle of low-voltage transformer.
  • Adopt 32 bit ARM processor, multi-channel 16 bit precision A/D convertor, high resolution TFT color LCD;
  • Inner equipped with 0.01% wide-range current transformer and can be equipped with various type current clamps, wide range of measurement and high veracity.
  • Low consumption circuit design, high energy Li batter supply, intellectual power management software, which make the instrument can continuously work up to 10 hours.
