This Multi-function LAN Cable Tester is a practical tool for measuring cable length, assessing PoE output, and checking wiring continuity in network cables. Its backlit LCD display provides clear, instant readings, and the auto shut-off feature preserves battery life for long-lasting use. Reduce troubleshooting time by quickly diagnosing network cabling issues with Continuity Testing to identify crossed wires, shorts, and open circuits. The Cable Tone Probe allows accurate tracing of cables, particularly in high-density setups. Non-Contact Voltage (NCV) detection helps identify AC voltage safely. Minimize delays by confirming PoE output before device connection. The PoE tester provides detailed pinout and voltage readings to ensure proper operation. Measure cable length (2.5m to 200m) and use the Port Flash/Switch Locator function to quickly trace and identify ports or switches. Compatible with Cat5e, Cat6, Cat6a, and Cat8 RJ45 cables, it supports both PoE and non-PoE devices. Ideal for on-site troubleshooting in enterprise, industrial, or data center environments, this portable tester reduces the need to carry multiple single-use tools. It is especially useful for field testing in remote locations, large facilities, or cramped spaces, streamlining network maintenance.
