Digital Cable Types of CableThree scan modes selectable: digital mode/analog mode/PoE mode. The NF-8209 works on CAT5e, CAT6, CAT6a (STP UTP), telephone, coaxial cable, and more. Finding the fault distance Hub turn signalMeasure the cable length and locate fault distance accurately for LAN cable. The range is 200m. Locate the network port by the flashing port light on the Hub/Switch. Available for 10m/100m hub/switch. PoE Range Information TestIdentify which pins supply power and detect how much voltage, identify PSE type (at/af) ; Identify the power supply voltage, power polarity, and mode of non-standard PoE devices. Test range of current, voltage and power consumed by DC devices. of standard DC5~60V/non-standard PoE device. Cable Continuity TestTest physical condition of LAN, UTP cable; check the status of short circuit, crossover and open circuit in the network cable. Non-contact voltage detectionPresence of NCV AC voltage (50V-1000V). The receiver can be used to detect the AC voltage of household electrical wiring.
