Class 0.3 Portable Reference Standard Meter , Portable Electric Meter 1.3kg

Portable Three Phase Reference Standard Meter on-site meter calibrator class 0.3


KE7301 Portable Three Phase Reference Standard Meter

KE7301 portable three phase standard meter is used for the test of three phase / single phase energy meters under class 0.5 and the inspection of circuit electrical parameters by electric power companies and institutes of metrology.

Main functions:

  1. Measure all kinds of meter, include single phase (1P2W) meter, three phase three wiremeter (3P3W), three phase four wire meter (3P4W) etc
  2. Current measure with clamp CT two mode
  3. Measure Vrms, Irms, phase angle, active power, reactive power, apparent power of three phase or single phase
  4. Measure total active power and total reactive power of three phase;
  5. Measure phase angle
  6. Measure frequency of power grid
  7. Display vector diagram
  8. Display waveform of voltage and current
  9. Analyze and display 2nd – 51st harmonic of voltage and current at real time
  10. Energy accumulating test (Dial test)
  11. Auto-check external wiring correct or not
  12. Test ratio of current transformer in low voltage circuit
  13. Wiring emulation, can simulate all kind of wirings on site without input voltage and current
  14. Realtime clock, accurate record testing time
  15. Store, browse and transfer measured data
  16. Real-time measured data by PC, and download calibration parameter
  17. Two kinds of power supply way: external AC power and voltage test lead power
  18. Support the barcode scanner to input number of energy meter automatically (option)
  19. Infrared scanning head (option)
