Armada PRO400 Handheld Graphical TDR Fault Finder

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. Features of the Pro400 include backlit display, auto off, calibration of VOP from 20 to 99%, 3 cable impedence level options, a virtually zero dead zone, and water/dust protection.  The Pro400 is truly a big bang for the buck.
