NF-300 is newly developed product which is able to avoid current interference,test BNC without noise. It is used in telephone system, computer networks and other metal lead circuits widely.
NF-300 LCD Display Telephone Network Error Cable Wire Tracker BNC tester Length Scanner without noise
The equipment is composed of 3 parts: main tester (NF-300), receiver (NF-300-S) and remote identifier (NF-300-R).
It has couples of circuit state testing functions including length test, cable line finding, line-to-line, cross talk and breaking point, serving as practical tool for low voltage system installation and maintenance technicians of communication circuits and comprehensive wiring circuits.
1. Capable to test open, short, cross connection, reverse, pairing connection and broken wire positioning (RJ11, RJ45, BNC Cable)
2. To perform crosstalk test on network cable to solve the potential problem of slow speed.
3. To quickly find the target wire or cable, coaxial cable up to 2500m, no need of remote unit when measuring length,
4. To trace cable on exchanger or Router without current interference.
5. Low voltage prompt function is available.
6. Functions of storage and memory.
7. Automatic delay power on-off and backlight function.
8. Language & light brightness can be set in the system.
9. Single chip software watchdog design runs reliably.
