Details
The position is adjusted according to the amount of deviation in X and
Y at the first point (model 0) detected in measurement 0.
There are three correction directions: X axis correction, Y axis
correction and X and Y axis correction.
· X axis correction--Adjusted misalignment in the X axis
· Y axis correction--Adjusted misalignment in the Y axis
· X and Y axes correction--Adjusted misalignment in both the X and Y
axes
The position is adjusted because of a detected angular deviation in
rotation [2-point search/2-point edge/1-point search + 1-point edge]
from measurement 0.

The high precision angular correction settings allows the IV-S20 to
display a very precisely corrected image. But, this selection lowers
rotation processing speed.

[5] Position correction
Based on the positional deviation data measurement 0 (positional deviation measurement), the
correction of the image coordinates is dealt with using measurements 1 to 3.

The types of position correction available are: XY correction, angular correction (standard) and
angular correction (high precision)
