Product Description
Three Phase Electric Meter Calibration equipment with Printer
GF312B portable three phase electric meter calibration equipment with printer is used to calibrate three phase, single phase, active and reactive watt meters. And it also can be used as voltage, current and power meter to measure AC parameters of three phase power line.It can measure wave distortion factor and 2nd to 63th harmonic wave.
Features
Three phase active or reactive electricity energy meter
Calibrate three phase, single phase, active or reactive meter error
Measure U(voltage) of three phase or single phase
4Measure 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 check measured data
Optional 5A, 20A, 100A, 500A, 1000A, 2000A, 3000A current clamp
