Product Introduction:
1, the measured frequency equivalent good. Test current waveform is a sine wave, frequency, frequency difference is only 5Hz, 45Hz and 55Hz using two frequencies measured.
2, anti-interference ability. The instrument uses a different frequency measurement, filtering techniques with modern hardware and software, making the instrument has a high resistance to interference, stable and reliable test data.
3, high accuracy. The basic error of only 0.005Ω, used to measure earth ground impedance small network.
4 powerful. Measure current pile, pile voltage, grounding resistance, step voltage, touch voltage.
5, easy to operate. Full Chinese menu operation, directly display the measurement results.
6, a small amount of wiring work, no large current line.
