Features: 【New Upgraded Multi-function Network Cable Tester】NF-8506 TDR network tester has IP scanning, POE test, cable tracking, continuity test, Ping test, network speed test, port flashing, sensitivity adjustment, cable function of length test and LED flashlight. 【Cable Length Measurement】The NF-8506 Network cable tester is a portable cable length tester. The cable tester can accurately measure the cable length in the range of 5-200m, find the cable fault distance and facilitate real-time field measurementt 【PING Tester+IP Scanner】This handheld Ping cable tester can be used to diagnose and maintain local area networks (Lans) running TCP/IP protocols. Powerful PING capabilities can verify connections, check the integrity of transmitted and received data, indicate network traffic load by measuring round-trip times and provide IP addresses 【Network Speed Test + Cable Continuity Test】Ethernet tester can quickly assess network speed issues. Conducts PING tests from multiple locations to gauge server and website response speeds. Allows users to ensure the integrity and connectivity of network cables by identifying any breaks, openings, or short circuits along the cable length. 【POE Tester】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. 【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.
