Suitable for telephone systems, computer networks, BNC cables, and other metal network cables. Cable length test: Works with metal cables that have at least two cores, including network cables, telephone lines, and BNC cables. Realtime measurement: Realtime network cable length measurement up to 400/600 meters, with short circuit and open circuit detection. Noiseless digital tracking: Uses advanced digital noiseless tracking technology to provide a smooth, reliable user experience. Essential for computer network and telecommunications cable installation, BNC cables, and other metal cable engineering. Use scenarios Data center or network room: quickly locate the correct cable among dense bundles during installation, rerouting, or maintenance. Site installation and troubleshooting: verify cable length and continuity for telephone lines, network cables, and BNC cables on location. Lab or : identify open or short circuits and confirm cable length to diagnose wiring faults.
