RJ45 RJ11 RJ12 CAT5 CAT 6 UTP Network Lan Cable Tester Test Tool Check for Rj45(network cable, UTP, STP), RJ11(telephone line), 2P, 4P, 6P, 8P Brand : KraijjaReatail Multi-functional Network Cable Tester Without Battery Functions : 1. Can test correspondingly double-twisted cables 1, 2, 3, 4, 5, 6, 7, 8 and G, meanwhile, can judge wrong connection, short circuit and open circuit. 2. NS-468 tests RJ 11and RJ45 Test of double-twisted cables Switch on the power. Put cables into both main tester and remote tester. The lights of the main tester will turn on sequently from 1 to G. Main tester: 1-2-3-4-5-6-7-8-G Remote tester: 1-4-3-2-5-6-7-8-G Following are abnormal connections: 1. If one cable, for example cable NO. 3is open circuited, the two NO. 3 lights of The main tester and remote tester will not turn on. 2. 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. 3.If two ends of a cable is disordered, for example NO. 2 and NO. 4, then displays on: Main tester: 1-2-3-4-5-6-7-8-G in tester: 1-2-3-4-5-6-7-8-G Remote tester: 1-4-3-2-5-6-7-8-G 4. If two cables are short circuited, neither of the corresponding lights is on of the remote tester while main tester remains unchanged. If three cables, including three, are short circuited, none of the corresponding lights is on. If test patch panels or wall plate outlels, two cables which can match each other(eg110 P4 and RJ45)will be connected to the tester.
