Precautions when using the multimeter buzzer to measure:
Before measuring, you need to make the multimeter value in the position of zero voltage or zero current. In the process of using the multimeter, do not touch the metal part of the test pen with your hands, which can ensure the accuracy of the measurement on the one hand, and personal safety on the other hand. When using the multimeter, it must be placed horizontally to avoid errors.
When using the buzzer to measure a circuit, the buzzer test does not need to measure with power on. In order to protect personal safety, the power supply of the circuit under test must be cut off during measurement.
