Precautions When Using The Power Fittings Ground Resistance Tester

Precautions when using the Insulation Accessories ground resistance tester:
1. Before measuring, the grounding device to be tested must be powered off, shut down, and the connecting bolts to the grounding wire must be removed.
2. In thunderstorm weather, the grounding resistance value of the lightning protection device must not be measured.
3. The connecting wires of the grounding electrode to be tested and its auxiliary electrode cannot be parallel to the high-voltage overhead line and underground metal pipeline to prevent interference or increase measurement errors.
4. The ground resistance meter generally does not perform open circuit tests.
