Draw a figure in the section to be inspected.
Do not include areas with marks and patterns in the measurement region. It
will not be possible to distinguish them from surface detects, and measure-
ment will not be performed properly.
Position detection can be performed using algorithms for detecting defects.
When a measurement region is drawn, measurement is performed for the dis-
played image and the results are registered as the reference values (X and Y
coordinates of the position where the defect was found). This position
becomes the reference position, so be sure to place the measurement object
in the correct position before drawing the measurement region.
1. Select Inspected region.
The Inspected Region Settings Screen will be displayed.

3. Draw a figure in the region to be measured.
Up to 3 figures can be drawn to create a region if Defect (region) has been
selected.
4. Select End.
The settings will be registered and the screen in (1.) will return.
The measurement region and the positions where defects were located will
be displayed. The defects will be indicated by a display cursor.
