A simple,powerful,tool that can troubleshoot network and telephone cables for broken wires and crossed connections-That is MCT-108 RJ11/RJ45 tester!Which including a main master unit as well as a detachable remote unit,powered with a 9-volt battery (not included) and can be stored in the zippered, synthetic leather case.Besides,both of the Master and Remote unit has a 9 LEDs that show the status of each line on the attached cable.It supports a fast automatic and a slow automatic mode.by paying the price which is currently selling at the much cheaper price than before,so its $10.99
How to use Tester to test a cable ?
1.Insert one end in the appropriate jack on the Master unit and the other in the same type jack on the Remote unit.Do not connect to a cable that is plugged into a live circuit as this may cause damage to the tester or other equipment on thecuit
2.Move the tester power switch to the “On” or “S” position. For best results, use the Slow Automatic mode (S position) to perform the test, as this gives time to watch the light sequence and ensure that the same LEDs illuminate on the Master and Remote simultaneously.
3.Watch the LEDS on both the Master and Remote units. Under normal conditions, using a straight-through RJ45 cable in good condition, the LEDs will simultaneously illuminate in the sequence 1-2-3-4-5-6-7-8-G on both the Master and Remote units.
4.A faulty or miswired connection will produce a different result, as follows:
a.If there a wire is broken or otherwise not connected the LED on the Master unit will illuminate, but no LED will illuminate on the Remote unit.
b.If a wire is crossed, different LEDs will illuminate on the Master and Remote units. For example, if the 3rd LED on the Master unit and the 5th LED on the Remote unit both illuminate then the wire is crossed between pin 3 on the Master side and pin 5 on the Remote side.
c.If there is a short circuit between two or more wires, no LEDs will illuminate on either the Master or Remote unit.
