11 3M Dynatel Cable Length Meter/ Time Domain Reflectometer 940CLM/TDR With the 3M Dynatel Cable Length Meter/Time Domain Reflectometer 940CLM/TDR, technicians of all skill levels can perform a variety of timesaving tasks when installing or maintaining metallic cable. This lightweight, hand-held tester: identifies most clear-opens or dead-shorts and displays the distance to the event in seconds instantly measures and displays cable length in feet or meters continually measures voltage to identify live circuits transmits four different tone frequencies and patterns to trace hidden cables or identify cable pairs includes selectable automatic powerdown options (5, 15, 30 minutes or continuous) The versatile, compact Dynatel 940CLM/TDR provides installation and repair technicians one simple device that meets several key needs. They can use it to detect faults up to a distance of 2500 feet (750 meters); determine the length of cable, whether in a box, on a spool or behind a wall; measure and display voltages of up to 250 volts rms; and transmit any of four tone frequencies to trace hidden cable in walls and ceilings. The 940CLM/TDR includes a convenient, built-in library of over 60 cable types. The technician selects the type of cable to test, attaches the test leads and receives a reading of cable length or distance to an open or short. Compatible with all common cables, it features standard banana jack connectors that accommodate a variety of leads or connectors. The 940CLM/TDR can save valuable installation time by enabling technicians to determine how much cable they have to work with and to detect shorts or opens in it before work begins, instead of taking the risk that they may have to start over after wiring is well underway. When used with the 3M Dynatel Subscriber Loop Tester 945DSP, repair 355 technicians can use the 940CLM/TDR to pinpoint a fault location. Both the Dynatel Subscriber Loop Tester 945DSP and the Dynatel Cable Length Meter/Time Domain Reflectometer 940CLM/TDR are part of 3M s complete family of industry-leading testing solutions for telco, CATV and electrical installations. 295
