How does multimeter measure the disconnection and mixing of communication cables?
Mixed line test method: basically consistent with the above, but also through the pass test.If your multimeter doesn't have a break test function, you can use a resistor shift, and the resistance value is very small
Line measurement methods: use a multimeter on-off test function, the pen is placed at the end of the two side, if the general guide is not broken, the conduction line may be broken (possibly mixed line)
