Pro400 Handheld Graphical TDR Fault Finder
Robust, Graphical, and Economical Time Domain Reflectometer
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.
