Overview NF-388 is a practical cable test & inspection instrument with lots of new functions researched and developed by our company, which is composed of tester (NF-388), receiver (NF-388-S) and remote identifier. It owns three great functions of wire hunting,wire sorting and circuit status testing quickly and accurately.
Main Functions and features One person enough to complete cable continuity check. Directly hunt 5E, 6E, telephone wire, coaxial cable, USB cable and other cables. Check wiring error in 5E, 6E, coaxial cable, such as open circuit, short circuit, jumper wire, reverse connection . Locate the wiring or connection error.
