The Wire Mapper Pro® Model CA7028 is a hand-held structured cable mapping and troubleshooting tester designed for use on UTP, STP, FTPand SSTP cabling equipped with RJ-45 connectors and wired to either TIA568A/B (ISO11801 and EN 50137), USOC or ISDN specifications. It detects open circuit pairs, shorts, crossed wires, crossed pairs, reversed pairs, split pairs and shield faults.

In the event of opens and shorts, the Model CA7028 uses TDR technology to indicate if the fault is at the near end or the remote end of the cable, or if it is somewhere in between. It will then indicate the distance to the fault. The Model CA7028 has the ability to measure and indicate the length of the cable under test, using a Vp (Velocity of Propagation) set by the user, from a built-in library or manually. It will measure and report the length of all four pairs of wires in the cable under test. It also generates an audible tone that is transmitted into all four pairs on the cable under test. This can be used for cable tracing and identification in conjunction with a tone receiver.
