The use of a multimeter can be divided into the following types: First, turn the knob to the AC voltage measurement position, perform mechanical zeroing, and when the value is zero, use the two probes to contact the live wire and the neutral wire of the circuit to be tested. Second, turn the knob to … Read more
1. Precautions for Using a Multimeter (1) Before using the multimeter, perform “mechanical zeroing”, which means setting the multimeter pointer to the zero voltage or zero current position when there is no measured electrical quantity. (2) During the use of the multimeter, do not touch the metal parts of the probes with your hands. This … Read more
