The Pro400 Graphical TDR is a great tool for locating faults in metallic cables with 2 conductors. Twisted pair, coax, LAN cabling, etc. are simple to test for distances to shorts, opens, etc. By connecting the leads to the cable to test, a graphical display quickly and easily shows faults and events on that cable. In addition, the Pro400 transmits a standard analog tracing tone for use with common tone probes to find the termination point of a cable.
