You can test cables with RJ45 or RJ11 plug. The device is fast and easy to use. With the help of LEDs, you can quickly identify the problem.
For example, if wire 3 is interrupted, LED 3 will not light on either the main or remote tester.
If the wires are reversed, for example 2 by 4, the main tester will light 1-2-3-4-5-6-7-8-G and the remote 1-4-3-2-5-6- 7-8-G.
If two or more wires are shorted, the corresponding LEDs will not light up.
To start the test, turn on the device from the switch, connect one end of the cable to the main tester and the other to the remote.
