Test twisted pair 1, 2, 3, 4, 5, 6, 7, 8, G root by root (right) to determine which (right) wrong wire, short circuit and open circuit. 2. Switch "OFF" indicates off, ON indicates normal test speed, and "S" indicates slow test speed. 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---------- (RJ11) If The Connection Is Abnormal, It Will Be Displayed As Follows: a. When one network cable, such as line 3, is disconnected, light No.3 on both the main tester and remote test terminal is off. b. If several cables are disconnected, none of them is on. If less than two network cables are connected, none of the indicators is on. C. If two network cables are out of sequence, for example, 2 and 4, the following information is displayed: Primary Tester Remains Unchanged: 1-2-3-4-5-6-7-8-G The remote test terminal is 1-4-3-2-5-6-7-8-G d. When there are two short circuits in the network cable, the main tester will not be on, while the two short circuits displayed on the remote test terminal will be on slightly. If there are more than three (including three), the lights of all short circuits will not be on. 4. If you are testing the distribution frame and wall base module, lead two matching jumpers (such as 110P4-RJ45) to the tester. 1 x 3 Way Network Cable Pliers 1 x Thread Clipper 1 x Wire Stripper 1 x Network Tester 10 x Crystal Head 1 x Storage Box 1 x Storage Bag
