Number of readings
•
Number of empty points
•
Number of obstructed points
•
Minimum thickness reading stored
•
Number of data points at the minimum thickness level
•
Number of thickness points below the min-thickness limit
•
Maximum thickness reading stored
•
Number of data points at the maximum thickness level
•
Number of thickness points above the max-thickness limit
•
Number of points with A-scans attached
•
Number of points with B-scans attached
•
Number of points with Micro-Grids attached
•
The mean, statistical range, and standard deviation of the
data contained in the data file (empty and obstructed points
are excluded from these calculations.)
