Wire Fault Locator Nf308s

Cable Fault Detection: Locates common issues like open circuits, short circuits, crossed wires, and reversed connections in cables such as CAT5e, CAT6, telephone, and coaxial. Wire Mapping: Displays the wiring order for RJ45 and other connectors to confirm correct pair configurations. Length Measurement & Fault Distance: Measures cable length up to about 1000 m and estimates where a break or fault is located. Polarity & Voltage Test: Tests DC polarity and can measure low voltages (around 0.5–60 V DC). Port Flash (Hub Blink): Helps identify which port on a hub/switch corresponds to a cable by detecting the blinking LED signal.
