Multifunctional Wire Tracker -- Quality Tool To Solve Your Life Problems The Ethernet Cable Tester is a versatile handheld network tester. It supports a wide range of applications for enhanced cable types and multiple functions. Not only the necessary test kits for telecom engineering, cabling engineering and network maintenance personnel, but also ideal for everyday life, such as telephone line cable testing, network cable tracking, TV cable and other weak electrical wires. Sensitive sensor, stable and reliable. With easy to operate and smooth appearance, the circuit finder and tracer is wide applicated in our life and work. The interface of the LAN tracker is flexible, switch is energy-saving and the high quality protecive case also provides more secure protection. Function Tracer function: This instrument is suitable for RJ11, RJ45, and other metal wires can be found through the transmitter. 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. Line function: the line detection is on the line of the open, shorted, wrong, reverse the physical connection detection.
