Echo ThruPaint™' mode, see Section 4.6 'Selecting the
Measurement Mode' on page en-8, B-Scan provides a
time-based, cross-sectional view of the material being tested.
Readings taken, saved readings, the highest (Hi), lowest (Lo) and
average (X) reading together with upper and / or lower limit
values (if set and enabled) are displayed.
The material thickness is illustrated by
grey and red shaded areas; red if
readings are outside limits (if set and
enabled). Readings which are saved
into the gauge or batch memory are
displayed as white or red vertical bars;
red if readings are outside limits (if set
and enabled).
The B-Scan vertical scale can either be set to 'Auto' or the user
can set the scale most appropriate for the thickness of the
material under test.
When the 'Start Depth' and 'Max Depth' are both set to 'Auto', the
scaling is determined by the minimum and maximum readings
taken.

1 Press Display/Setup Display/B-Scan Scaling/B-Scan Start
