What is the buzzer in the multimeter for?
The buzzer file of the multimeter is mainly used to check the continuity of the line. When checking the line, use the buzzer file to measure. If the digital multimeter beeps, the line is connected. If there is no beep, the circuit is open. of.
It should be noted that the buzzer will beep under a certain resistance value, generally tens of ohms. Therefore, when measuring a resistance with a very small resistance value, do not think that the resistance is broken, and you should use the resistance file to check at this time.
