NOYAFA

• Professional Wire Tracker. It can help you quickly find the target line in many pairs. It is suitable for tracking RJ45 internet cable, RJ11 telephone line and other metal wire in low electricity. Please note that it can not be used to track wires with high electricity ( maximum currents for emitter and receiver are 10mA and 30mA respectively, and maximum voltage is 10V ). Besides, you may need two 9V laminated cells, which are NOT included in the packaging of this item.
• Network Cables Verifying. Plug one side of the cable into the emitter and the other side into the receiver. Select "Network" to check and verify whether the network cables are good or not. No need of network tester.
• Wire Tracking. It can trace not only Ethernet LAN wires, but also electrical and speaker wires when connecting to the alligator clip. In this situation, the wires must be in power-off status, otherwise the units will be damaged. It is recommended to stripe down some of the wires when connecting through the clip. Select "SCAN". Emitter works properly if the "SCAN" indicator is on. Use the receiver to find target wires. No need of multi-testers.
• Telephone Line Test. The work of the telephone line of the detection of various states, only the transmitter can be detected, such as determining TIP or PING line, to determine the work of the telephone line idle, ringing and off-hook state.
• Additional Earphone & Equipped Lamp. In a noisy environment, you can put on the earphones to accurately find the target cable through comparing the strength of "beep beep" sound. Adjust the volume knob to make the volume proper and avoid being interfered. At night or in a dark environment, you can turn on the illuminating lamp, which can be helpful during operating.
