How to use a digital clamp meter to check the user's internal lines and equipment for leakage
Use a leakage current clamp meter to measure the leakage current value at the user's power inlet line, and at the same time, put the user's electrical equipment and lamps in and out one by one, and find the leakage current value by looking at the change of the leakage current value measured by the leakage current clamp meter. equipment or lamps; if all the equipment and lamps are normal, or the equipment with leakage has been withdrawn, but the leakage current clamp meter shows that the user still has leakage current, it may be that the user's low-voltage line has leakage and should Deal with it on a case-by-case basis. For the leakage fault of pre-buried and hidden pipelines, the only way to deal with it is to change the line or re-wiring.
