Multi-Function Cable Tester Tone Detection LAN Telephone

Network Line Test & Multi-Function Design : Conduct end-to-end validation of Ethernet and telephone cables with automatic sequence checking. The multi-function interface allows switching between test modes for open/short detection, polarity verification, and continuity checks on various cable types. Advanced Tone Detection with Earphone : The included earphone delivers high-fidelity audio feedback, allowing precise identification of the target wire in congested or noisy environments. Adjust the volume to match ambient conditions and rely on consistent tone recognition for accurate results. Safe Wire Tracer Operation : Operates exclusively on de-energized or low-voltage circuits (under 24V), ensuring user safety and device protection. Ideal for tracing irrigation control wires, dog fence cables, or hidden metal conduits without risking electrical hazards. Efficient RJ45 RJ11 Testing : Supports direct connection to standard network and telecom jacks. The device quickly verifies pinout correctness and detects common wiring faults, making it perfect for post-installation quality assurance in structured cabling projects. Integrated Diagnostic Features : Combines cable testing, current detection, telephone line analysis, and LAN wire search in a single handheld unit. This integration reduces tool clutter and increases diagnostic speed in both residential and enterprise environments.
