🔧 AT278 Network Tester: A Comprehensive Multi-Functional Tracker for Efficient Network Testing Review

⏩【Fault Distance Measurement】Our Network Cable Tester utilises TDR theory to accurately measure cable length with visual length graphics and provide distance to fault information. Display graphical wire mapping, opens, shorts. BUT PLEASE NOTE: our device works by TDR theory, which is mainly to test long cables. If cable is <20m, it will display cable is too short or open. Thus, when measure length, pls try a long cable, for other functions, short cables are acceptable. pls kindly notice this. ⏩【POE Testing】AT278 Network Cable Tester can detect Ethernet network for POE(Power over Ethernet) existence and to know which pins are providing power and detect how much voltage. ⏩【PING Function 】AT278 Cable Tester is designed for testing network performance, data packet, min & max time. Test the reachability of a host on an Internet Protocol(IP) network. It reports errors, packet lost, and a statistical summary of the results, including the minimum, maximum, the mean round-trip times. ⏩【AC Filter】Trace cables with AC fliter, quickly find the targeted cable without AC noise. Available on common switch & PoE Switch. Also, it is safe to find cable in standard types of PoE switches, which won't burn out the device. ⏩【Aditional Highlights】Come with TF card included to export data to PC; Voltage detector: included in receiver (90-1000V); Rechargeable Lithium battery for more efficient work. Low voltge alarm function and automatic delay power on-off. Big LCD color screen 320*240 and lighting lamp in darkness. Hub blink to locate network port by the flashing port light on a server/switch/hub/router port.
