Multifunction RJ45 RJ11 network cable tester, Cat5 Cat6 Ethernet LAN line tracer with earphones, for network maintenance

Multifunctional Wire Tracer: Quickly locate the break point without damaging the cable sheath. Find wires on all types of Ethernet network switches, routers, and PC terminals. Perfect for tracing RJ11, RJ45, cables, or other metallic wires (via adapter). Also features a positive and negative battery voltage measurement function (10V-110V).

Wire Tracer: The line locator can trace not only Ethernet LAN wires but also electrical wires and speaker wires when connected to the alligator clip. In this case, the wires must be unplugged, otherwise the devices will be damaged. It is recommended to strip some of the wires before connecting through the clip; select "scan"; the "scan" indicator will work correctly; use the receiver to find the target wires.

Network and Telephone Line Testing: The line locator tests the physical connection status of the network cable, such as open circuits, short circuits, faulty connections, and reverse connections.

Use the transmitter to test the functionality of telephone lines (such as checking for TIP or ring lines), test line strength, and detect positive and negative polarity. Adjust the receiver volume by pressing the rotary volume knob. Headphone Design: With a pair of headphones, you can simply connect them to the receiver's headphone jack for clear information in noisy environments. Adjust the volume knob to achieve the correct level and avoid interference. Note that if the sound is low, you should check if the battery is on. The LED flashlight allows operation in the dark.
