POE Test Verifies cable mapping polarity and PoE voltage of PoE network switches, helping you confirm correct power delivery and wiring quickly. Cable Length Test Applies to various metal cables with at least 2 cores, including network cables, telephone lines, and BNC cables. Provides length and continuity information to aid routing, fault finding, and installation planning. Multifunctional Cable Tester Combines analogue tracing, cable mapping, and PoE voltage measuring in one device, with digital tracing sensitivity that can be adjusted for precise identification and testing in different environments. LCD Display with Flashlight Large LCD display for easy reading plus a builtin flashlight to illuminate work areas in low light, improving visibility during installation and troubleshooting. Use scenarios PoE installations: Verify PoE voltage and correct cable mapping when wiring PoE devices such as IP cameras or PoE switches, reducing downtime and wiring errors. Office cabling and maintenance: Map wall outlets, check cable continuity and length, and identify miswired or damaged cables in networking and telecom setups. Field testing of diverse cables: Test network cables, telephone lines, and BNC cables on site to locate faults and confirm compatibility with the tester's functions.
