On - Site Portable Meter Tester Class 0.3 Single Phase Meter Calibration 100A Clamp
On - Site Portable Meter Tester Class 0.3 Single Phase Meter Calibration 100A Clamp
KE7202 Portable Single Phase Reference Standard Meter
Accuracy : 0.3, Test method: clamp CT input. It's light and small, making it convenient for on-site test, and can be used to test the error of single phase energy meters and field electrical parameters of power grid.
Functions:
- Current measure with terminal input or clamp CT
- Display waveform of voltage and current
- Analyze and display 2nd - 39th harmonic of voltage and current at real time
- Energy accumulating test (Dial test)
- Real time clock, accurate record testing time
- Store, browse and transfer measured data
- Two communicatio port: USB and RS-232
- Real-time measured data by PC, and download calibration parameter
- Test lead power or external power for choices
- Support the barcode scanner to input number of energy meter automatically (optional)
