- 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.
- 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.
- High precision, intrinsic error 0.005Ω, can test the ground network of small impedance.
- Powerful: can test current pile, voltage pile, ground resistance, pace voltage, contact voltage.
- Easy to operate, menu operated, directly display the test results.
- Do not need high current wire.
