- To increase the speed of your search, you must take into account the settings listed
below.
1. When using the high precision setting, a smaller image should be used.
2. Reduce the size of the scanned image.
3. After considering what the maximum out of position dimension would be, make the
search area as small as possible.
4. If the size of the object is larger than 8 pixels then set the pixel contraction to "3".
Ë Ë Ë Ë Ë Measurement programs which are affected by these settings
Positional deviation measurement (gray scale search), degree of match inspection, lead inspection,
multiple position measurement, and multiple degree of match inspection.
