Multimeter detects wire short circuit
1. Detection method
Separate the cores of the two ends of the wire, be careful not to cross or touch each other, then hit the multimeter to the position above (picture 1), and put the test pens on the two different colored wire ends. Short-circuit measurement operation.
The multimeter detects the short circuit of the wire and gives the result in seconds without effort
2. Test results
A measurement of 0 indicates a short between the two wires. If the measurement result shows infinity, it means there is no problem with the line.
3. Matters needing attention
When measuring the short circuit of the circuit, first turn off the main gate of the power supply, then adjust the switch of the multimeter to 1 or 10 ohms, and measure the two wire ends of the same group of circuits. If the resistance is almost 0, it means a short circuit.
Basic measurement method:
Use the ohm x1 gear of the multimeter to measure the two ends of the line. If the resistance value is close to zero, it is a short circuit. When there is a certain resistance value (depending on the load in the line), it cannot be judged whether it is a short circuit or not. When the voltage is constant, the resistance value The smaller it is, the greater the current flowing through the line.
Use the ohm 1k or 10k gear of the multimeter to measure the two ends of the line. If the resistance value is infinite, it means an open circuit.
