Thông tin chi tiết
NF-308 multipurpose network cable test & inspection instrument is the latest cable test & inspection instrument with lots of new functions researched and developed by our company.
The equipment is composed of tester (NF-308), receiver (NF-838-R) and remote identifier. The new instrument is provided with fluent appearance, excellent hand feel and considerate human-centered design.
It owns three great functions of hunting, wire sorting and circuit status testing and the features of quickness and accuracy, thus, it becomes available tool for technicians in installation and maintenance of weak current system, such as, communication line, comprehensive wiring circuit, etc.
It is widely applicable to telephone system, computer network, other metal wire circuit and other fields.
Main Functions and features
●One person enough to complete cable continuity check.
●Directly hunt 5E, 6E, telephone wire, coaxial cable, USB cable and other
●Check wiring error in 5E, 6E, telephone line, coaxial cable, USB cable
and such as open circuit, short circuit, jumper wire, reverse connection
or cross-talk interference.
●Locate the wiring or connection error.
●Measure cable length and determine the distance of open circuit and
●Dynamically calibrate cable length and make length measurement as
accurate as 97%.
●Simple and easy use. Big screen to display test result clear.
●Portable unit with long battery life (wait-case 50 hours).
●Automatically time-delay shut off and backlight display function.
●Measure length and pair with or without far-end recognizer.
●Locate cable and there are 8 far-end passive test jacks (ID No.ID1-ID 8).
●Far-end recognizer with prompting voice.
●Self-checking function and automatically compensate any change in
battery capacity or ambient temperature.
