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