This meter combines with the cable tracing and cable length measuring functions. The advantage of this meter is the long-tracing distance clear sound signals quick and precise cable length measurement. The 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. The cable tracing function can quickly and efficiently find the 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: The cable tracing function can quickly and efficiently find the 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. POE Test: POE testing can check cable mapping polarity and voltage of POE network switches. Multifunctional Cable Tester: This cable tester has the function of analogue tracing, cable mapping, PoE voltage measuring, digital tracing sensitivity adjustable, etc. LCD display with Flashlight: The sender of this line finder adopts a large LCD display screen to give you a better experience and the flashlight allows you to turn it on when the light is low. Multimeter Function: This function includes direct current and AC voltage and current measurement, resistance, continuity, diode, temperature measurement. 500M network cable length measuring ranges. ID Pairing Function: Comes with 3PCS ID pairing accessory for you to achieve ID pairing function easily.
