248 Cable Tester Automatic Scanning RJ45 RJ12 RJ11 Network Wires Detector Tracker DC 9V Item Type: Cable Tester Material: ABS shell Model: 248 Test Cable: RJ45, RJ12, RJ11 Power Supply: DC 9V laminated battery (Delivery without battery) Power Consumption: 25MA Test Methods: 1. Test the twisted pairs 1, 2, 3, 4, 5, 6, 7, 8, G one by one (pair) to determine which one (pair) is wrong, short circuit or open circuit. 2. The switch OFF is closed, ON is the normal test speed, 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, as shown in the figure below: 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, Will be Displayed as Follows: a. When there is a network cable, such as line 3 is broken, the main tester and remote test terminal No. 3 lights are not on. b. When several lines are unavailable, several lines will not light up. When the network cable is less 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 short circuits, the main tester does not light up, and the two wires on the remote test terminal show that the short circuit lights are dimly lit. If there are more than 3 wires (including 3 wires), all short circuited wires will be short circuit. The lights of several line numbers are off. 4. To test the distribution frame and wall mount module, two matching jumpers (such as 110P4‑RJ45) are required to lead to the tester.
