Item Type: Line Finder Material: ABS Model: NF-468 Battery: 6F22 1 x 9V (not included) Purpose: Network cable, telephone line detection and testing Language Version: English Testable Cables: Network cable, telephone cable, video cable Display: LED flashes Current: 25mA Maximum Withstand Voltage: 60V Test Speed: Normal, slow (adjustable) Network Test: RJ45/RJ11 Scanning Method: Automatic How to Use: 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. 2.NF-468V can be tested: RJ45, RJ11 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. 4. Push the side switch for lighting function. 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. Test method (take RJ45 as an example) 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 Flashing one by one in order, as shown in the figure below: Main tester: 1-2-3-4-5-6-7-8-G Remote Test Terminal: 1-2-3-4-5-6-7-8-G If the wiring is not normal, it will be displayed as follows 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. 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. 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 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 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
