Basic mode provides the simplest means of operation for pre-locating most cable faults. The TDR provides step-by-step operation instructions, automatically sets the cable end points, displays the cable length in feet or meters and displays the distance to the cable fault from the hook-up point. The auto range feature fits the cable trace on the screen, regardless of the cable length.

The operator is then prompted to send a single, high voltage pulse down the cable. The TDR displays the high voltage trace, places a fault cursor at the point of the fault, and displays the distance to the fault. There is no need to interpret traces or move cursors. The entire process can be completed within minutes.

Advanced Mode operation provides the operator with complete control and setup access of the TDR functions and settings. Typically this is used in cases where the cable type may be unknown, the cable system has a complex system configuration (loop and network systems) or where the fault may be intermittent. It is password protected to prevent unauthorized use. This mode provides more experienced operators with the diagnostic tools they need to find more difficult faults.

TDR functions that can be adjusted include: propagation velocity, pulse width, gain, 3-phase or single-phase display,and trigger delay. Zoom and cursor features are also fully available to the user in Advanced Mode. In addition alternate languages, memory functions, selectable measurement systems and much more are accessible.
