Set the conditions for judging the correlation of the measurement object to the
model. The judgement conditions will be shared by all 5 models.
Set the range between 0 and 100, with 100 for objects that perfectly match the
model. If the correlation is equal to or above the judgement condition set here,
the judgement result will be OK.
Position Compensation Judgement Results and Scrolling
OK: Scroll will be performed.
NG: Scroll will not be performed. The overall judgement will be NG, regardless
of the measurement result.
The settings method is the same as for Not Rotate. Refer to page 2-9-(7).
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).
Position compensation can also be performed in the rotation direction by
searching for characteristic features on the circumference using defect algo-
rythms.
The difference between defect (circle) and defect (arc) is the search region.
For circles, the circumference (360 ) is searched and for arcs, an angle range
is specified.
