Description

LAN Network Cable Tester RJ11 RJ12 RJ45 Cat5 Networking Tool

Can test correspondingly double-twisted cables 1, 2, 3, 4, 5, 6, 7, 8andG, meanwhile, Can judge wrong connection, short circuit, and open circuit.
Can test RJ 11and RJ45
Test of double-twisted cables: Switch on the power. (S is slow automatic grade, Mis manual.)
Put cables into both the main tester and remote tester. The lights of the main tester will turn on sequentially from 1 to G.
Main tester: 1-2-3-4-5-6-7-8-G
Remote tester: 1-2-3-4-5-6-7-8-G RJ45
1-2-3-4-5-6 RJ11

If one cable, for example, cable NO.3 is open-circuited, the two NO.3 lights of the main tester and remote tester will not turn on.
If several cables are not connected, several lights will not turn on respectively. If less than two cables are connected, none of the lights is on.
If two ends of a cable are disordered, for example, NO. 2and NO. 4, then displays on:
Main tester: 1-2-3-4-5-6-7-8-G
Remote tester: 1-4-3-2-5-6-7-8-G
If two cables are short-circuited, neither of the corresponding lights is on of the remote tester while the main tester remains unchanged.
If three cables, including three, are short-circuited, none of the corresponding lights are on.
If test patch panels or wall plate outlets, 2 cables that can match each other (RJ45) will be connected to the tester.
If test cables of the same axes, BNC turns on when the cable works.
9V reduplicated battery is used in this tester. The battery is to be changed if any weak light appears (Battery is not included.)
