1. Good frequency equivalence. The measured current waveform is sine wave, the difference between frequency and power frequency is 5Hz, use 45Hz and 55Hz two frequency to test.
2. Strong anti-jamming ability, use different frequency method , assorted with modern hardware and software filtering techniques, make the device with strong anti-jamming ability, test results stable and reliable.
3. High precision, intrinsic error 0.005Ω, can test the ground network of small impedance.
4. Powerful. can test current pile, voltage pile, ground resistance, pace voltage, contact voltage
5. Can measure the field disturbance, user estimate measuring error conveniently.
6. With the disconnection alarm function, the error measurement is avoided.
7. Easy to operate, menu operated, directly display the test results.
