Handheld Portable 3in1 Network Cable Finder Cable Length Measuring Instrument Multimeter LCD Display with Backlight Analogs Digital Search POE Test Cable Pairing Sensitivity Adjustable Network Short Circuit Open Circuit Measure Trackers Multifunctional Ca This meter combines with the cable tracing, cable length measuring and multimeter functions. The advantage of this meter is the long-tracing distance clear sound signals, fast 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: 3.5inch LCD Display with Flashlight: The sender of this line finder adopts a large LCD backlight display to give you a better experience and the flashlight allows you to turn it on when the light is low. Multimeter Function (Optional): This function includes direct current and AC voltage and current measurement, resistance, continuity, diode, NCV, temperature measurement. Multifunctional Cable Tester: This cable tester has the function of analogue tracing, cable mapping, PoE voltage measuring, digital tracing volumes and sensitivity adjustable, automatic shutdown, and cable length self-calibration function. Cable Tracing & Signal Changeable: 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. And support set the frequency for using on tracing. Cable Length & Pairing Check: Able to measure cable length, test open circuit, short circuit, cable sequence and cable break. Voltage Test: Check the polarity and voltage of battery or cellphone lines. Continuity Test (OHM): Check open circuit or short circuit of cellphone lines(cellphone line should not be connected to any power source). 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 the network cable length measuring ranges of 600M. POE Test: POE testing can check cable mapping, polarity and voltage of POE network switches.
