W hile in the B-Scan mode, pressing the Up ARROW key will eliminate the
Minimum Thickness display. The B-Scan will run approximately 25 percent
faster. The graphic representation of thicknesses can be approximated from
the scale on the left axis of the display.
Pressing the DOW N ARROW key eliminates the horizontal and vertical
scaling dots. This action increases the scrolling speed an additional 10
percent (approximately), although any horizontal reference will be lost.
Blank sections in the B-Scan presentation are generally an indication of
poor coupling. To become more familiar and proficient with the B-Scan
feature, practice on a stepped-wedge will help.
