gaoshang Network cable tester NF-466SPOEEE, suitable for Ethernet, telephone lines, shielded cables and optical fibers, supporting POE anti-burnout protection Analogue Battery Tester

Full-line intelligent detection, precise fault location Can test each individual twisted pair wire 1-8 cores + shielded G ground wire, accurately identify open circuits, short circuits, and line sequence errors, three common network cable faults, and intuitively distinguish faulty lines. Without the need for repeated troubleshooting, quickly locate wiring problems, significantly improving the efficiency of network cable maintenance. Compatible with all specifications of network cables, shielded/non-shielded universal. Also supports UTP non-shielded network cables and STP shielded network cables for testing. Home network cables, engineering monitoring cables, and office twisted pair cables can all be compatible; shielded network cables can simultaneously detect the connection status of the shielded ground wire G, meeting the testing needs for all scenarios in home decoration, weak current engineering, and office wiring. Plug and play without operation, minimalist design without physical power switch The body has no physical power switch. After installing a 9V battery and inserting the network cable, it can automatically start the detection and start the test immediately after insertion, eliminating the steps of turning on and off. The operation threshold is extremely low, and electricians and weak current beginners can quickly master it. No additional operation or debugging is required for outdoor maintenance. Built-in POE fire protection, safe and durable use Equipped with POE fire protection circuitry. When testing monitoring network cables and switch lines with POE power supply, it can withstand high-voltage return shock and avoid instrument burnout; in the engineering site, it is more reassuring to measure wires while energized, extending the equipment's service life and reducing maintenance costs. Stable signal, anti-interference, no data transmission delay The test signal has strong anti-interference ability and is not affected by strong electricity or electromagnetic interference from equipment around. The test results do not flash or report errors; the indicator lights flash synchronously and orderly, and the fault feedback is real-time and accurate, ensuring the authenticity and reliability of the wiring test results.
