LHT2571 Electronic 10W Digital Lightning Protection Grounding Resistance Tester Meter IP67 0.2 Accuracy 2-Year Warranty
1. In order to prevent power frequency and radio frequency interference, a phase-locked loop synchronous tracking detection method is adopted in the circuit, and a switch capacitor filter is used to make the instrument have good anti-interference ability; 2. Using DC/AC conversion technology to convert DC into AC low-frequency constant current for easy measurement; 3. Allow the auxiliary grounding resistance to vary between 0~1.8K Ω (RC) and 0~40K Ω (RP), without affecting the measurement results; 4. The grounding resistance tester does not require manual adjustment of balance, with a 3 (1/2) position LCD display. In addition to measuring ground resistance, it can also measure low resistance conductor resistance, soil resistivity, and AC ground voltage. If the test circuit is not functioning and the meter displays "1", it indicates overflow, which is in line with conventional measurement habits.
