Wire Fault Locator

The **NF-308S Wire Fault Locator** is a handheld cable tester and tracer used by network installers, electricians, and IT technicians to find, test and diagnose faults in communication and data cables. It supports tracing and checking **Ethernet (RJ45), telephone (RJ11), coaxial and USB cables**, detecting open circuits, shorts, crossed or reversed wires. The device measures approximate cable length and estimates the distance to a fault using TDR-style technology, displays results on a backlit LCD, and includes features like port-flashing to help identify network ports and polarity/DC voltage testing. It comes with a transmitter, receiver probe and remote identifiers for on-site cable troubleshooting.
