4.3 Min Scan and Max Scan
Measurement Modes
These modes allow the user to continuously evaluate
material thickness then, when the evaluation period
is complete, display the extreme (minimum or
maximum) material thickness observed. During the
evaluation period, thickness is displayed along with
the minimum and maximum observed thickness
values (Figure 4-2).
Measuring Thickness
Min Scan and Max Scan Measurement Modes
FIGURE 4-2—MIN SCAN and MAX SCAN allow observed measurements and display the maximum and
minimum thickness encountered during the period. The time-out feature (represented by the bar shown
here) allows a momentarily uncoupling during the evaluation period, and then recouple to continue the
same period. In these modes the instrument will continue to collect and compare readings for as long as the
probe remains coupled.
