The Digital Multimeter, You Can Set Breakpoints

DMM can not only measure voltage, current, resistance, capacitors, transistors and other basic settings, but also through the alternative use can extend the functionality of it, becoming a multi-function meter.

Today I introduce a way to determine how the breakpoint of the rope or cable.

When some breaks with the conductor, as an outer conductor is a package of insulation and determine the exact location of the break point was very hard. We can use a digital multimeter to help solve the problem. Specific methods are as follows: to the other side of the conductor that is connected to a breakpoint on the firing line is 220V, and put the other half floating in the air. You can set the profile digital multimeter AC-2V, where to get a hand in the line of fire is started, in another hand to hold the meter point black pen, rather than a red pen to move the external support package gauge isolation This time the voltage is approximately 0.445V. If the meter red pen to move somewhere where the voltage is suddenly dropped to just 0.0 volts, which appears on the screen, so that we can to a certain position of the break point is a forward-15cm along the side of access, which is in the firing line.

If you use this method to verify the shield, it will not help in this situation, which shattered all over and the screen is not broken.
