Item Type: BNC Network Cable Tester Material: ABS Shell Model: NS-468B Test Cable: RJ45 RJ11 Power Supply: DC 9V Laminated Battery [Delivery Without Battery] Power Consumption: 25MA How to Use: Test Methods: 1. Test the twisted pair 1, 2, 3, 4, 5, 6, 7, 8, G one by one (pair) to determine which one (right) is wrong, short circuit or 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 the remote tester respectively, the indicator lights of the host 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 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 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 circuited. 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. 5. Coaxial Cable Test: If the cable is good, the BNC lights at both ends will flash green at the same time.
