The ohm range of a multimeter is often used to confirm the two ends of a wire to determine whether they are the same wire.
method:
1. Turn to the ohm position;
2. Align the meter --> When the two ends of the test leads touch each other, the meter will make a sound.
3. Touch the two wire ends with the test probes respectively. If the meter makes a sound, it proves that there is only one wire.
Summarize:
1) In engineering, the wires are usually very long and it is impossible to find the other end along one end of the wire. This method is used to determine whether it is the same wire.
2) During the project, sometimes one end of the wire is inserted into the pin, and the probe tip is too thick to reach the pin. At this time, you can find any wire without cutting it specifically. Just take the head of a bundle of wires and insert it into the pin, and then touch the probe tip to the wire.
