Title: Network Cable Tester PoE Cable Tester NCV for CAT5 CAT6 CAT7 CAT8,Ethernet Cable Finder Test Length Measurement Product description: This meter combines the cable tracking and cable length measurement functions. The advantage of this meter is the long range clear sound signals fast and precise cable length measurement. The meter is a practical tool for laboratories,factories,radio enthusiasts,network installers and technicians. It can measure network cable length,short circuit and circuit interruption in real time. The cable search function can quickly and efficiently find the target cable in a large number of cables. This feature can be used in telephone systems,computer networks,BNC cables and other metal network cables. Features: Cable tracking function: 3 digital scan modes,both analog and PoE modes for easy cable tracking. Also included are cable length measurement,continuity test,voltage test,cable fault test,PoE test,stroke blink and NCV function,making it an indispensable tool for cable engineers. POE test: The POE test function can test the cable allocation polarity and voltage of POE network switches,withstand 60 VDC,and locate network ports by flashing the network indicator (flashes every two seconds) on hubs and switches. Automatic detection and switching between 10M/100M/1000M modes. Cable length test: Real-time measurement of network cable length (up to 400 m/1312 ft) and built-in short circuit protection. This function can be applied to various metal cables with at least two wires,including network cables,telephone lines and BNC cables. Dual-torch LCD display: Features a large LCD display for easy reading,a flexible and versatile user interface and an adjustable volume control for noisy environments. Both the monitor and the receiver have a lamp to solve the problem of working in the dark. The monitor contains a built-in 1250mAh 3.7-V lithium battery. The receiver is powered by a 9-V battery (included). Widely used: The cable tracking function can find the target cable in a large number of cables quickly and efficiently. This device is widely used in telephone systems,computer networks,BNC cables and other network cables. Track and locate underground or wall-mounted cables. Perfect for security monitoring,communication cables,integrated cabling and other low current systems.
