Cable Length Tester NF-868B

NF-868B type multipurpose communication cable tester & tracker has couples of circuit state testing functions including length test, cable line finding, line-to-line, crosstalk and breaking point and features fast and accurate, and thus serves as a practical tool for low voltage system installation and maintenance technicians of communication circuits and comprehensive wiring circuits. It is widely used in the fields like telephone system, computer networks and other metal lead circuits.
♦Capable to test open circuit, short , cross connection, reverseconnection and pairing connection and broken wire positioning .
To make a accurate determination of open circuit position (left, rightor middle).
To quickly find the target wire or cable among the plenty of wires.
To perform crosstalk test on network cable for solving the potentialproblem of slow speed.
Capable to measure length of network cable, coaxial cable, telephonecable and USB cable with three method (M-S, M-R and OPEN).
To perform cable tacking on exchanger or Router with power-on.
Utomatic delay power on-off and backlight function.
Self test function shall automatically make compensation due tochange of battery level and ambient temperature.
