1、The measured power frequency equivalence is good. Test current waveform is sinusoidal wave, and the frequency only differs from the power frequency by 5Hz. 45Hz and 55Hz are used for measurement.
2、Strong anti-interference ability. Ground Network Earth Resistance Tester adopts different frequency method to measure, and with modern software and hardware filtering technology, the instrument has high anti-interference performance, and the test data is stable and reliable.
3、High precision. The basic error is only 0.005 & Omega; , can be used to measure the earth network with low grounding impedance.
4、Powerful. Measuring current pile, voltage pile, grounding resistance, stepping voltage, contact voltage.
5、Easy to operate. Chinese menu operation, direct display of measurement results.
6、Small wiring labor, no need for large current line.
