Specifications

Description:
NF-308, cable test & inspection instrument with lots of new functions, is composed of tester (NF-308-M), Receiver (NF-838-R) and remote identifier. It owns three great functions of hunting, wire sorting and circuit status testing.  thus, it becomes an 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 features:
1.One person enough to complete cable continuity check.
2.Directly hunt 5E, 6E, telephone wire, coaxial cable, USB cable and other cables.
3.Check wiring error such as open circuit, short circuit, jumper wire, reverse connection.
4.Determine the distance of open circuit and short circuit.
5.Length measurement of network cat5 and cat6.
6.Simple and easy use. Big screen to display test result clear.
7.Portable unit with long battery life (wait-case 50 hours).
8.Automatically time-delay shut off and backlight.

Length Measurement of
Twin Twisted Cable:
Scope: 1~350 M (3 ~200 ft); Calibration accuracy: 3% (+/- 0.5M or +/- 1.5 ft) (calibrating cable > 5 M); Shipment accuracy: 5% (+/- 0.5 M or +/- 1.5 ft). (AMP, AT&T Class 5 cable)
Length Calibration:
 User can set calibration factor by himself with a given length cable. The length of calibrating cable is more than 5M.
