KE7302 Portable Three Phase Reference Standard Meter
 
Accuracy : 0.2, Test method: clamp CT and terminal input. It's light and small, which is convenient for on-site test, and can be used to test the error of three phase energy meters and field electrical parameters of power grid.
 
Features:

1. Measure all kinds of meter, include single phase (1P2W) meter, three phase three wiremeter (3P3W), three phase four wire meter (3P4W) etc
2. Measure the current with clamp CT and terminal 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)
