This meter combines with cable tracing and cable length measuring functions. advantage of this meter is long-tracing distance clear sound signals quick and precise cable length measurement. meter is a practical tool for laboratories factories radio lover network installers and technicians. It can real-time measure network cable length short circuit and circuit break. cable tracing function can quickly and efficiently find target cable in a large number of cables. This function can be used in telephone systems computers networks BNC cables and other metal network cables. Features: Cable Tracing Function: cable tracing function can quickly and efficiently find target cable in large number of cables. This function can be used in telephone systems computers networks BNC cables and other metal network cables. Cable Length Test: This function can apply to different metal cables with at least 2 cores including network cables telephone lines and BNC cables. With network cable length measuring ranges of 600M. POE Test: POE testing can check cable mapping polarity and voltage of POE network switches. Multifunctional Cable Tester: This cable tester has function of analogue tracing cable mapping PoE voltage measuring digital tracing sensitivity adjustable etc. LCD Display with Flashlight: sender of this line finder adopts a large LCD display screen to give you a better experience and flashlight allows you to turn it on when light is low.
