How does the multimeter detect the short circuit of the wire
The method of testing the open circuit: turn the switch of the multimeter to the resistance gear, connect the red test lead and the black test lead to the two ends of the red line respectively, when the multimeter shows 0, it proves that the line is good, and when it shows infinity, it is an open circuit, and the other two lines have the same method. .
Short-circuit test method: separate the cores of the two ends of the wire, do not touch each other, then hit the multimeter to the position above and above, and put the test leads on the two different colored wire ends, if the measured value is 0 , it proves that there is a short circuit between the two lines, and if it shows infinity, it proves that the line is good.
