1. The structure of the instrument is made of high-strength aluminum alloy. In order to prevent the interference of power frequency and radio frequency, the phase-locked loop synchronous tracking detection mode and the switch capacitor filter are used to make the instrument have better anti-interference ability;
2. DC / AC conversion technology is used to change DC into AC low frequency constant current for easy measurement;
3. The auxiliary grounding resistance is allowed to change between 0 ~ 1.8KΩ(RC) and 0 ~ 40kΩ (RP), which will not affect the measurement results;
4. This grounding resistance meter does not need manual adjustment of balance, and 3 (1 / 2) LCD display can measure the resistance of low resistance conductor, soil resistivity and AC ground voltage in addition to the ground resistance. If the test loop is not connected, the indicator "1" indicates overflow, which conforms to the conventional measurement habit.
