• ★【SENSITIVE & PROFESSIONAL】High Sensitivity And Strong Anti-jamming Ability for Identifying the Target Wire Among Plenty of Wires Rapidly. Remotely test cable up to 1000 ft in length. It's adaptable to RJ45 terminal & RJ11 terminal and other metal wire in low electricity. Please note that it can not be used to track wires with high electricity (max currents:10mA- 30mA, and max voltage is 10V ).
• ★【EASY TO OPERATE】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. There are only 2 buttons on the emmiter,FUNCTION SLECETING & FUNCTION SWTICHING, and 1 INCHING button on the receiver. The indicating words such as "SCAN" and "TEST" are clear and easy to identify.
• ★【VARIOUS USES】☑ Wire Tracking: Connect the wire to the emitter through alligator clips. Select "SCAN". Emitter works properly if the indicator "STATUS" is on. Use the receiver to find target wires. No need of multi-testers. ☑ Network Cables Verifying: Plug one side of the cable into the emitter and the other side into the receiver. Select "TEST", the emitter works properly if the indicating light "VERIFY" is on. Determine circuit problems from numerous cables. No need of network tester.
• ★【CONVENIENT DESIGN 】☑ Low-Voltage Reminding & Energy Saving. Select "SCAN", the "STATUS" indicator and the "VERIFY" indicator will flash at the same time when the cell voltage is below 6V. It will automatically switch off while not using; ☑ 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.
• ★【WIDE USE】Can Be Used to Trace A Wide Range of Cable Includes Telephone Wire, Computer Network Cable, TV Cable, Perfect for tracking RJ11, RJ45, cables or other metal wire (via adapter); There Are Many Useful Functions Such As Continuity Testing, Network Cable Sequence Collation, Open/Short Circuit Testing And DC Level Testing.
