Multi-function Cable Tester. Provides a range of essential cable testing and diagnostic functions in one device, including cable tracking, cable continuity testing, cable length testing, PoE checking, PING, port flashing, and more. Ideal for various applications such as network maintenance, data centers, and equipment upgrades. Line Tracking Capability .Accurate detection of both shielded and unshielded network cables. Offers standard and interference-resistant line tracking methods for versatility. Useful for engineering cabling tasks. Cable Continuity Testing Allows users to ensure the integrity and connectivity of network cables by identifying any breaks, open circuits, or short circuits along the cable's length. Accurate Cable Length Testing Determines the length of network cables upon insertion. Supports cable length testing within a range of 8.2ft / 2.5m - 656ft / 200m. Simplifies cable length measurement process. PoE (Power over Ethernet) Testing. Identifies PoE devices efficiently. Detects crossover methods (unknown/end-span/mid-span/8-core power supply) and polarity. Comprehensive PoE detection, including non-standard, IEEE 802.3AF, and IEEE 802.3AT. Network Ping Testing. Quickly assesses network speed issues. Conducts PING tests from multiple locations to gauge server and website response speeds. Port Flashing and Identification.Facilitates quick identification of network cable ports. Indicator lights on the connected port in the device flash to help locate cables accurately. Displays port information including operating rate, duplex mode, and negotiation settings. NCV (Non-Contact Voltage) Sensing Pen. Detects live circuits safely and accurately. Identifies live equipment, wires, and sockets with a single button press. Helps prevent accidents caused by high voltage during construction. High-Intensity LED Lighting. Equipped with a built-in electroplated s
