Loznron Cable Tracer Ethernet Network Cable Tester Battery Jumper Cable  (Plastic)

【Wire Network Cable Tracer】In SCAN mode, this wire cable tracker can accurately trace wire or cable among messy lines and quickly diagnose the breakpoint without stripping the cable sheath. It can trace the cable with RJ11, RJ45, and BNC terminal or other metal wire through the adapter. It can directly trace wire when a weak current device is turned on, such as an Ethernet switch, router, and PC terminal. Please note: Do not use it on strong strong live circuit. Batteries are not Included. 【Line Status Tester】In TEST mode, this Ethernet tester can intuitively test the open circuit, short circuit, missing wire, reverse connection of the line through 18 line sequence indicator lights. It can be used as a continuity tester to test the continuity of the cable or wire. It can also be used as a phone line tester to identify the state of the working telephone line (clear, ring, busy) and judge the TIP or RING line . Can test the positive and negative polarity of the DC level. 【Quick & Accurate Network Cable Sequence Collation】this network tester supports POE below 60V to directly calibrate the line sequence. It uses digital signals to solve the problem of finding shielded wires (G is a shielded wire test light). You can quickly find the required cables in the cable bundle, under the carpet, on the decorative wall, and on the ceiling. Widely used in telephone systems, computer networks, communication cables, and other occasions involving metal wire lines. 【With Earphone and LED flashlight】This Ethernet wire toner with earphones helps you receive signals better in a noisy environment. Adjust the volume knob to make the volume appropriate and avoid interference. By comparing the strength of the "beep beep" sound, the target cable can be accurately found. Note, if the sound is very small, you should check whether the battery is out of power. At night or in a dark environment, you can turn on the LED flashlight to work.
