How to find leakage current with a multimeter?
Leakage of what? If it is to measure whether an object is charged (electricity to the ground), turn on the multimeter to the appropriate range (depending on the occasion), the black means the white is grounded, and the red pen is connected to the measured object. Electricity. If it is to measure whether there is an electrical leakage to the ground wire, check whether there is current in the ground wire. If it is a clamp meter directly clamped to the ground wire to measure, if it is a common multimeter, then the ground wire must be cut off, and the multimeter will open the AC current gear (be careful, the protection of the metal shell electrical appliances will be lost after the ground wire is cut off), and the two ends will be disconnected. Connect it to the two test pens of the multimeter, if there is a reading, it means there is leakage. Of course, this method is very troublesome, it is better to install a leakage protector.
