  • Page 9: Chapter 1 Overview

    Chapter 1 Overview 1.1 Product Overview The Hioki 3665-20 LAN CABLE HiTESTER is a hand-held cable tester that provides easy operations to test wiremap, measure cable length and identify twisted-pair cables. It is useful for veri- fying connections after installing connectors on cables. Optional terminators are available to facilitate easy identification of multi- ple cables.
  • Page 10 1.1 Product Overview Testing cable connections after installing connectors Checking wiremaps (p.19). Troubleshoot cables in working networks When an open- or short-circuit fault is present in a cable, the HiTester displays the distance along the cable from it to the fault. So when a problem occurs in a working network, the HiTester determines whether the problem is caused by an open- or short- circuit in the cable, and its location (p.29).
