The 62-200 LinkMaster is a basic wiremapper for identifying wiring and continuity errors in twisted pair cabling. Wiremappers are used to verify if the cable is physically terminated properly at both ends and that there are no major cable defects present in the cable, such as cut conductors, that would prevent signal continuity. Colored LED lights identify pass or fail conditions of each pair of wires in RJ-45 8 conductor cables. When the test is activated, LinkMaster checks each pair of the cable for any opens (unterminated or cut conductors), shorts (cut or nicked conductors that come into contact), miswires (wires out of order - not consistent at both ends), reversals (one pair miswired), split pairs (wired correctly but using wrong conductor order and grouping). Single button operation simplifies the use of the LinkMaster. Includes main test unit and remote unit.
