Noyafa / NF-308R / LCD Wire Fault Locator

Noyafa NF-308R LCD Wire Fault Locator | All-in-One Cable Tester

The Noyafa NF-308R LCD Wire Fault Locator is a professional, multi-function cable testing and fault location instrument built for network engineers, electricians, and IT technicians. Specifically, it serves as a single reliable tool to hunt cables, diagnose faults, and measure cable lengths across complex wiring systems. It directly hunts Cat5e, Cat6, telephone wire, coaxial cable, and USB cables, while also checking for wiring errors such as open circuits, short circuits, jumper wires, and reverse connections. Furthermore, to round out your testing kit, you can explore our networking tools for additional diagnostic equipment.

Dual Scan Modes in the Noyafa NF-308R LCD Wire Fault Locator

Additionally, the Noyafa NF-308R LCD Wire Fault Locator highlights its versatility through two scan modes: Tone Tracking and Port Flashing. The tone frequency operates at 455 kHz, achieving a maximum transmission distance of 2 km and a cable map distance of 300 m. The Port Flash function identifies exactly which port on a live switch or router a specific cable connects to by matching the flashing LED on the port panel. Consequently, tracing cables in fully patched racks and live network environments becomes fast and accurate without disconnecting any active links.

Advanced Diagnostics & Smart Features

Moreover, this versatile unit measures cable lengths up to 1000 meters and locates the exact distance to any breakage point, dramatically reducing fault-finding time in large installations. A polarity test function measures DC voltage from 0.5V to 60V, complete with memory storage for your calibration data. Therefore, reading your results is easy on the large 128×64 character LCD screen, which presents all test data clearly in any lighting condition. The automatic time-delay shutoff and backlight display extend battery life, ensuring the Noyafa NF-308R LCD Wire Fault Locator remains reliable throughout extended field use. Finally, with compatible connectors including RJ11, RJ45, BNC, and USB, this device delivers everything a field technician needs in one compact package.
