Position and Rotation Adjustment
Position and rotation adjusters find the difference of adjustment required between the
coordinates recorded as setup (reference point) and the coordinates found when
executed. Individual checkers come under a position and rotation adjuster group, and
by applying the amount of adjustment, checker coordinates can be adjusted by an
appropriate amount for inspection. The detection methods available for position and
rotation adjusters are binary edge checkers, gray edge checkers, feature extractors,
and matching. (Settings for base checker.) Base checkers with different methods of
inspection cannot be combined into one position and rotation adjuster. For instance, for
position adjustment, it is not possible to use a binary edge checker for horizontal
adjustment and a feature extractor for vertical adjustment.
14 different position and rotation adjuster modes are available with different types of
base checker and different methods of inspection.

Note
In order to make the appropriate adjustments, the Multichecker
uses checker functions to provide position and rotation
adjustment.
Consequently, you need to be aware of the functions of
inspection checkers in order to set adjusters.
If you are using checkers for the first time, first read the
descriptions of checkers starting from Smart Matching
and Gray Scale Edge Checkers, in order to gain an
understanding of how checkers work.
