This tester is a multi-functional wire tra-cker, including cable emitter and receiver. It has functions like telephone wire tracking, network wire tracking, power cable tracking, network wire check, etc. and it produces fast and accurate measurements. It is a necessary testing tool for telecommunication engineering, wiring engineering and network maintenance person.

Features:
Can test telephone wire, network wire, power cable.
Can test the line level, positive and negative polarity by using emitter only.
Equipped with RJ11 cable and with BNC/RJ45 interface.
Network wire checking function to judge normal/short-circuit/open-circuit/crossing and reverse connection.
Easy and fast to locate the breakpoint without opening the wire's cover.
Includes low Ba-tte-ry indication function.
Protected by a bag, portable to carry.
