How to use a multimeter to test whether an electrical appliance is leaking?
The easiest way is to use a test pen. It is better to use a multimeter. It can measure the voltage of leakage. The method is: connect the red test lead to the electrical appliance, and the black test lead to ground. If there is no ready-made ground wire, it can be connected to the water pipe. The meter is placed at the voltage level of 250V. If it cannot be measured, gradually reduce it. In this way, you can know whether there is leakage and the degree of leakage.
