Nickname: Grounding Grid Resistance Tester; Grounding Resistance Meter
Features
1. The measured power frequency has good equivalence. The test current waveform is a sine wave with a frequency difference of only 5 Hz from the power frequency. Two frequencies of 45 Hz and 55 Hz are used for measurement.
2. Strong anti-interference ability. The large-scale ground network grounding resistance tester adopts the different frequency method for measurement, combined with modern software and hardware filtering technology, which makes the instrument have high anti-interference performance and stable and reliable test data.
3. High precision. The basic error is only 0.005Ω, which can be used to measure the ground network with a small grounding impedance.
4. Powerful. It can measure current pile, voltage pile, grounding resistance, step voltage, and contact voltage.
5. Simple operation. All Chinese menu operation directly displays the measurement results.
6. The wiring labor is small, and no large current wire is needed.
