Specification: Item Type: Network Cable Tester Material: ABS Test Cable: RJ45 RJ11 Power Supply: DC 9V laminated battery (not Included) Power Consumption: 25MA Test Methods: 1. Test twisted pairs 1, 2, 3, 4, 5, 6, 7, 8, G one by one/pair, which can determine which one is right/wrong, short circuit and open circuit. 2. The switch OFF is closed, ON is the normal test speed, and S is the slow test speed. 3. Twisted-pair test: Turn on the power, plug the network cable into the main tester and remote tester respectively, and the host indicator lights will flash from 1 to G one by one, for example: 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 wiring is not normal, it will be displayed as follows: a. When a network cable such as line 3 is disconnected, the main tester and remote test terminal No. 3 lights will not light up. b. When several lines are unavailable, several lines will not light up. When the network cable is l than 2 lines connected, the light will not light up. c. When the two ends of the network cables are out of order, for example 2, 4 wires are out of order, the display is as follows: The main 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 the network cable has 2 sho Package List 1 x Network Cable Tester 1 x English Manual 1 x Case 1 x Accessory
