Circle Position Compensation
Section 2-9
Element Sizes and Comparing Pitch
When a region is drawn on the circumference, a box (element) is automatically
drawn inside the region. The density of each element is calculated and the
position of defects is detected by comparing the element with surrounding ele-
ments and looking at differences in densities.
Changing to Other Modes (Clearing Settings)
The settings must be cleared before changing to another mode.
The settings method is the same as for Not Rotate. Refer to page 2-9-(8).

Circular Angles
Another circle is drawn in addition to the circle for external positioning. A char-
acteristic feature on the circumference of the new circle can be used for posi-
tion compensation in the rotation direction.
The densities of neighboring elements are compared
and the difference in density becomes the element
defect value for the element with the greater density.
The element with the largest defect value is recognized
as the characteristic portion for rotation positioning.
