The NF-488 PoE checker is consists of two parts: an Emitter and a remote. It has functions such as standard and non-standard PoE equipment detection, PoE power online test, network cable continuity test, DC power test, switch loop-back test and other functions. Therefore, it is a perfect for security monitoring, communication wires, integrated wiring and other weak current systems. Features: Test the information of the standard/non-standard PoE device, such as voltage, polarity, midspan or endspan. Identify the type of PSE, it is af or at standard. Test of real-time power consumed by PD devices in PoE power supply systems. Test the open, short, cro status in the network cable. Test the power consumed by DC appliances. The loop test function of the switch.
