The Ermenrich NetGeeks NP40 multifunctional is a digital cable tester designed to trace twisted pair and telephone cables, to test lines for faults and installation errors, to measure cable length and distance up to the point where an interruption (open circuit) has occurred or a short circuit is present. This tool will prove to be very practical for technicians who implement and maintain a computer network or telephone network within an office, an entire building or a home.
In its basic operating mode, this tool can check for damage on individual electrical wires within a cable: open circuits, short circuits, twisted pairs. Using the cable length measurement mode it is possible to measure the total length of the cables within 200 meters, as well as the distance to the fault point. If necessary, calibration and TDR (time domain reflectometry) measurements can be performed with high accuracy.
The flash port function can be used to precisely find the port of the network switch or router to which the cable in question is connected. The PoE test identifies the PSE type and detects the midspan/endspan link. This meter can also measure voltage and polarity. The tester's receiver can be set to NCV mode to detect the presence of voltage without any contact.
The transmitter and receiver are powered by batteries (not included).
