• If the variability for good workpieces is large.
Decrease [Candidate LV].
• If there are large differences in the shape of individual workpieces.
Raise [Acceptable distortion level], if th
e co
rrelating value is decreased
when you change the work Piece.
• Except for the work pieces shape can be detected.
Raise [Edge Level], if work’
s
dirty point or fine patterns are miss-detected.
• It could be not able to measure in pixel unit.
Check [High-Prec.], if the accuracy of
mea
surement coordinates is low.

• Detected target can be found too much.
Raise [Acceptable distortion level] if miss-detected is occurred
,
e.g. place where is
no work piece or similar to wo
rk piece shape are detected.
• Miss-detection can be occurred because there are many edges back on work pie
ces
P target edges are not able to be detected.
