On - Site Portable Energy Meter Test Equipment Three Phase 45Hz - 65Hz Class 0.1

 On - site portable energy meter test equipment Three Phase with 100A clamp CT class 0.1

KE7303 Portable Three Phase On-site Electric Meter Tester
 
Accuracy : 0.1, Test method: clamp CT and terminal input. It's light and small, which is convenient for on-site test. And it can be used to test the error of three phase energy meters and field electrical parameters of power grid.
 
Product descriptions:

1. Calibrate the error of all electricity energy meters, checking the constant of the energy meter
2. Simultaneous checking of the primary meter and the secondary meter in the same loop, or simultaneously checking of the active power meter and reactive power meter inthe same loop
3. Can measure voltage, current, frequency, power, power factor and phase angle
4. Simultaneous measure and display waveforms of three phase voltage and current
5. Detectthe error change of the clamp automatically; ensure the accuracy stability ofthe clamp and the instrument in the long run.
6. Measure ratio of CT, VA burden of the metering loop from VT and CT secondary terminals.
7. Allocate clamp of 20A, 100A, 500A, 1000A to directly measure the comprehensive error
8. Can measure 2^nd – 51^st harmonics of current and voltage
9. Display vector diagram, verify the wiring
10. Battery, test lead power or external power for choices
11. Communicate with PC, download calibration data through USB flash disk, RS-232 or bluetooth
12. Firmware can be upgraded through removed disk by users themselves
13. Save and browse the testing data, data storage quantity is up to 1000 pieces.
