Item Type: Line Finder_x000D_ Material: ABS_x000D_ Model: NF-468_x000D_ Battery: 6F22 1 x 9V (not included)_x000D_ Purpose: Network cable, telephone line detection and testing_x000D_ Language Version: English_x000D_ Testable Cables: Network cable, telephone cable, video cable_x000D_ Display: LED flashes_x000D_ Current: 25mA_x000D_ Maximum Withstand Voltage: 60V_x000D_ Test Speed: Normal, slow (adjustable)_x000D_ Network Test: RJ45/RJ11_x000D_ Scanning Method: Automatic_x000D_ How to Use:_x000D_ 1. Twisted pair 1, 2, 3, 4, 5, 6, 7, 8, G wire pairs are tested one by one (pair), and it can be distinguished and judged which one (right) is wrong, short circuit and open circuit._x000D_ 2.NF-468V can be tested: RJ45, RJ11_x000D_ 3. Long press the power button for 3 seconds to start the test, touch the power button again for the slow gear test, touch the power button again for the manual test, and press the power button for 6 seconds to shut down._x000D_ 4. Push the side switch for lighting function._x000D_ 5. The MIC USB interface next to it is the power supply interface, which can be directly powered by a power bank or other devices._x000D_ Test method (take RJ45 as an example)_x000D_ Install the 9V battery, buckle the battery cover, press and hold the switch to turn on the power to the normal test speed, touch the switch to switch the slow test mode, and insert the plug of the cable to be tested into the main tester and the remote test terminal. The indicator lights of the main tester flash from 1 to 8 one by one. If it is a shielded network cable (STP), the indicator lights of the main tester flash from 1 to G_x000D_ Flashing one by one in order, as shown in the figure below:_x000D_ Main tester:_x000D_ 1-2-3-4-5-6-7-8-G_x000D_ Remote Test Terminal: 1-2-3-4-5-6-7-8-G_x000D_ If the wiring is not normal, it will be displayed as follows_x000D_ When a network cable such as line 3 is disconnected, the light 3 of the main tester and the remote test terminal will not be on._x000D_ 2. When several wires are not connected, the corresponding lights of the main tester and the remote test terminal are off. When the network cable is less than two wires connected, the lights are off._x000D_ 3. When the two ends of the network cables are out of order, for example 2, 4 lines are out of order, the display is as follows_x000D_ The main tester remains unchanged: 1-2-3-4-5-6-7-8-G_x000D_ The remote test terminal is: 1-4-3-2-5-6-7-8-G_x000D_ 4. When two or more network cables are short circuited, the main tester's display remains unchanged, and all the lights of the corresponding line numbers that are short circuited at the remote test terminal are not lit
