NF-488 POE Tester for Power Over Ethernet, Network Cable Continuity Checking, Switch Loop-Back POE Detector

NF-488 PoE Tester is a practical tool for installation and maintenance of technical personnel in security monitoring, conmunication wires,integrated wiring and other weak current systems.

Main Functions:

Test the information of the standard/non-standard PoE device, such as voltage, polarity, mid-span or end-span.
Test of real-time power consumed by PD devices in PoE power supply systems.
Test the open, short, cross status in the network cable.
Test the power consumed by DC appliances.
The loop test function of the switch


Power Testing Test the voltage and current between the power adapter and the powered device, and calculate the power consumed by the powered device	LED lighting LED lights can be used at night or in dark environments to meet your testing needs in various environments	Testing Results as Below Figure 1 shows, #12 is short-circuited, #45 is short-circuited Figure 2 shows, #5 broken-circuited, #8 broken-circuited Figure 3 shows, #18 crosses, #56 crosses Figure 4 shows, Good condition
