1. Professional POE Network Cable Tester The RJ45 network cable tester is designed to shorten cable testing and troubleshooting time for those with testing needs. It integrates POE testing, continuity (CONT), power function, loopback testing, and LED lighting into one device. Equipped with an RJ45 remote interface, no additional preparation is required. Compatible with CAT 5e, CAT 6/6A cables. 2. POE AND LOOPBACK TEST This PoE tester is designed to test standard PoE devices, including AF/AT standards, power supply voltage, polarity, and mode, supporting up to 60VDC. It can automatically detect and diagnose loopback issues and switch between 10M/100M/1000M modes. The RJ45 tester also features cable tracing, shortcircuit testing, opencircuit detection, loopback testing, and more. 3. Cable Continuity Detection Function Connect the network cable to the transmitter, and the PoEenabled wire tracker automatically detects short circuits, crossovers, and open circuits, displaying the status on the LCD screen for precise line positioning and connection verification. 4. Voltage, Current, and Power Tester This Ethernet tester can measure voltage, current, and power between the power supply and powered devices, as well as calculate power consumption from DC devices. Voltage detection range: 060V DC; Current measurement range: 03A; Power measurement range: 0180W.
