Wide Compatibility:Equipped with an upgraded high-performance chip for accurate wire continuity, miswiring, and connection fault detection. Compatible with RJ45 network cables (Cat5, Cat5e, Cat6, Cat6A, Cat7) and RJ11/RJ12 telephone lines (Cat3, 6P2C/4P4C/6P6C).

Accurate Wire Mapping (UTP/STP):Identifies common wiring issues such as open circuits, shorts, miswiring, and crossover connections. Works with both unshielded and shielded cables (UTP/STP), making it ideal for LAN diagnostics, installation, and maintenance.

POE Power TEST:Supports POE voltage detection up to 36V, enabling quick identification of power supply type and real-time operating status of POE switches. Intuitive LED indicators provide clear visual response for fast diagnostics.

Clear LED Display:The bright LED indicator system delivers clear and easy-to-read results for quick fault detection. The intuitive design is suitable for both professionals and beginners handling home or network installations.

Power Supply Note:Operates with a 9V battery (not included) for reliable performance. For safe operation, ensure the tested PoE or network cable voltage does not exceed 36V to avoid potential damage to the device.
