The grounding down lead is the connection part between the power equipment and the grounding grid. During the long-term operation of the power equipment, the connection may be affected by damp and other factors, resulting in node corrosion and even fracture, resulting in the increase of the resistance of the connection point between the grounding down lead and the main grounding grid, which can not meet the requirements of the power regulations, resulting in unsafe hidden dangers in the operation of the equipment, and in serious cases, the equipment will lose ground.
Precautions for grounding down lead continuity tester:
1. Before using the instrument, please read the instructions carefully and connect according to the correct wiring method in the instructions.
2. During the test, please confirm that the tested equipment has been powered off and disconnected from other live equipment.
