GF312D1 HANDHELD THREE PHASE ENERGY METER CALIBRATOR The instrument is a precision AC energy meter testing instrument, mainly used to test three phase energy meter error on site and measure all various of AC parameters. FEATURES AND FUNCTIONS Three phase active or reactive electricity energy meter. Calibrate three phase, single phase, and 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. Measure 2-64 harmonic of U, 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 Lithium battery supply, intellectual power management software, which enables the instrument continuously working up to 10 hours.
