How does the multimeter measure the short circuit to ground, how does the multimeter detect the short circuit of the wire
In daily electricity use, there are sometimes problems of short circuit or open circuit. At this time, a multimeter can be used to measure the circuit, and the short circuit or open circuit can be detected through the numerical display or the sound of the buzzer. The method is simple and practical.
Multimeter to measure short circuit to ground
1. Is the circuit broken?
Measure between two wires in the line, hit the resistance gear or diode buzzer gear, if the value shows close to 0 ohms or the buzzer sounds, the line is unblocked, otherwise the value shows 1 or the buzzer does not sound, The line is not smooth and there is an open circuit.
2. Whether the line is short-circuited
Hit the resistance gear or the diode buzzer gear, and measure between the two lines of the line. If the value shows close to 0 ohms, the buzzer sounds, indicating that there is a short circuit fault between the lines.
When a multimeter is used to measure the short circuit to ground or there is an open circuit, the value shows 1 or the buzzer does not sound, it means that the two lines of the line are normal and there is no open circuit problem.

Multimeter detects wire short circuit
Separate the cores of the two ends of the wire, be careful not to touch each other, hit the multimeter to the position above and above, and put the test leads on the two different colored wire ends respectively, and measure the circuit condition.
If the measurement result shows 0, it means there is a short circuit between the two lines, and if it shows infinity, it means the line is normal.
The above is the method of measuring short circuit to ground with a multimeter, and using a multimeter to detect short circuit of wires. I hope it will be helpful to everyone.
