The Ermenrich NetGeeks NP30 cable tester is designed for checking network cables, finding open circuits and measuring the length of a cable. The device is useful for anyone who installs computer networks and phone lines, maintains, fixes bugs, and can also be used for home use.

The Ermenrich NetGeeks NP30 can be used for testing network, telephone, coaxial and other cable types. It can be used to check open circuits and short circuits as well as swapped and crossed pairs. There is a port flash feature that allows you to find the exact port on the network switch or router to which the destination cable is connected. The length measurement is available for LAN cables from 5 to 350 meters with an accuracy of 5%. It is also possible to calibrate the device to increase the accuracy of the measurements. The cable tester can also measure the distance to open circuits.

The set contains a transmitter, a receiver, a remote control and other accessories. The transmitter and receiver each require a 9V battery (batteries not included)

Features:

• Measurement of cable length by measuring the capacitance of a cable
• Can be calibrated to improve measurement accuracy
• Cable diagnostics: open circuits, crossed pairs, short circuits
• Localisation of an open circuit, measurement of the distance to it
• Port flash function to determine the exact port on the network switch or router to which the target cable is connected
