Product Description
KE7304 portable three phase standard meter is used for the test of three phase / single phase meters, electrical parameter of the power line, the transformer ratio by electric power companies, meter manufacturing companies and institutes of metrology.


  • Calibrate the error of all electricity energy meters, checking the constant of the energy meter
  • Measure voltage, current, frequency, power, power factor and phase angle
  • Simultaneous measure and display waveforms of three phase voltage and current
  • Measure ratio of CT, VA burden of the metering loop from VT and CT secondary terminals.
  • Allocate clamp of 5A,  20A, 100A, 500A, 1000A, 1500A to directly measure the comprehensive error
  • Measure the 2nd - 21st harmonics of current and voltage
  • Display vector diagram, judge the wiring right or wrong automatically
  • Read the information of energy meter with barcode scanner (optional)
  • Battery, test lead power or external power for choices
  • Communicate with PC, download calibration data through USB flash disk or RS-232 port
  • Firmware can be upgraded through removed disk by users themselves
  • Save and browse the testing data
