Summary:
Grounding resistance meter is a safe instrument produced according to the principle of potential compensation. It is simple to operate and easy to carry. It is widely used to measure the grounding resistance of single grounding body and centralized grounding body. The measurement of grounding resistance is an important measure to monitor the grounding quality and ensure the safety of electricity. The national verification procedure of grounding resistance meter is jjg366-2004.
Jdb-2 grounding resistance meter verification device is a standard instrument for verification of grounding resistance meter, which fully conforms to the requirements of jjg366-2004 for the standard device, and can be used to verify analog and digital grounding resistance meters of various accuracy levels and models. It shall not be used for verification of grounding on resistance meter (working current is AC25A).
Can be used for resistance box, the starting resistance of 10 m Ω, distinguish between 1 m Ω eed.
