How does a multimeter measure leakage
First disconnect the main switch of the power supply, then connect the connector of the multimeter to the terminal, and then use one test lead to measure the zero line or the ground line, and the other test lead to measure the leakage position. If the multimeter shows 0, it means there is no leakage. If it shows 36V or 220V, it means that the meter is leaking electricity, and it should be dealt with immediately.
