statistical data related to each data file:

• 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.)

To view the statistical properties listed above:

Step 1:

Open the Data Recorder by pushing .

Step 2:

Activate the STATS Submenu by selecting it with
