Time Domain Reflectometry (TDR). This is a
measurement technique which detects
common cabling problems such as open
circuits, short circuits and impedance
mismatches or breaks in transmission cables.
The distance from the option to the error is
displayed in metres with an accuracy of +/- 2m.
The value 0 means no errors detected.
