Three Phase Handhled Energy Meter Tester accuracy 0.3 electric meter calibration

KE7304 Three Phase Handheld Energy Meter Tester

Accuracy : 0.3, Test method: clamp CT 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.

Product information:

1. Measure voltage, current, frequency, power, power factor and phase angle
2. Simultaneously measure and display waveforms of three phase voltage and current
3. Display vector diagram, judge the wiring right or wrong automatically
4. Measure the 2nd -21st harmonics of current and voltage
5. Realize energy accumulation test
6. Measure ratio of CT
7. Able to calibrate the error of all electrical energy meters
8. 3 power supply choices: rechargeable battery, test lead power or external power for choices
9. Communicate with PC via RS-232, download calibration data through USB fl ash disk
10. Adopt automatic recovery technology, the equipment can be recovered automatically after trouble is solved
11. Testing data can be saved on the instrument for later query. Max data storage quantity is 1000 pieces.
