Precautions for how to measure leakage with a multimeter
When testing the front circuit, make sure that the circuit is in a power-off state, and live operation is strictly prohibited.
When using the pointer multimeter, hit the R×10 gear, the digital multimeter will have a buzzer, you can directly use the buzzer gear or use the resistance gear.
When using a multimeter to measure whether the circuit is open circuit, short circuit or leakage, pay attention to the correct insertion method of the test leads. The black test lead is inserted into the COM jack, and the red test lead is inserted into the measurement voltage resistance jack. Do not insert the wrong test lead.
The above is the method of using a multimeter to measure open circuit, short circuit and leakage, I hope it will be helpful to everyone.
