KE7302 Three Phase Portable Meter Tester
 
Accuracy : 0.2, Test method: clamp CT and terminal input. KE7302 is used to calibrate three phase, single phase, active or reactive energy meter, and also it can be used as voltage, current and power meter to measure AC parameter of three phase power grid.
 
Advantages:

1. Measure all kinds of meter, include single phase (1P2W) meter, three phase three wire meter (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
