(described below).
Base model instruments offer four display modes. In
addition, two more display modes are available
depending on the installed options. Display modes
include:
NORMAL (Thickness Only) – The thickness value
appears as large digits in the center of the display. No
live A-Scan is displayed but an A-Scan snapshot of
the triggering echo can be accessed (Section 4.2).
MIN SCAN (Minimum Thickness Scan) – Allows the
user to continuously evaluate material thickness
(provided the probe remains coupled or is uncoupled
only briefly) then, when the evaluation period is
complete, the minimum material thickness is
displayed. During the evaluation period, thickness is
displayed along with the minimum and maximum
observed thickness values (and the calculated
difference between the two). The display also includes
a time-out bar, which begins to fill as soon as the
probe is uncoupled. Recoupling the probe before the
time-out period expires allows the user to continue with
the same evaluation period. When the evaluation period
is complete (after the probe is uncoupled and the time-
out bar fills), the minimum thickness observed during
the evaluation period is displayed. Its corresponding A-
Scan can also be displayed by pressing . At this
point the screen is frozen. Recouple the probe to
reactivate the display screen (Section 4.3).
MAX SCAN (Maximum Thickness Scan) – Allows the
user to continuously evaluate material thickness
(provided the probe remains coupled or is uncoupled
only briefly) then, when the evaluation period is
complete, the maximum material thickness is
displayed. During the evaluation period, thickness is
displayed along with the minimum and maximum
observed thickness values (and the calculated
difference between the two). The display also includes
a time-out bar, which begins to fill as soon as the
probe is uncoupled. Recoupling the probe before the
