10.10 Auto Find
The DFX-7 is equipped with a very handy feature for locating the detection point of a
back wall echo that is not currently in the viewable region of the display. Suppose
the DFX-7 is currently setup with a delay of 0.0” and a width of 1.0”, and the user is
measuring material thickness of 2.5”. The DFX-7 will make the correct measurement
and display it digitally. However, the waveform will not show up at all in both A-Scan
views, and incorrectly in the B-Scan view without adjusting the range of the Delay
and Width accordingly.
