Edge Pitch Section 2-27
2-27-5 Changing Detailed Conditions
Change the detailed conditions when the measurement results are unstable.
Normally, these conditions can be left on the default settings.
If any of the settings are changed, take actual measurements to confirm that
they are correct.
1. Select Detailed conditions.
The Detailed Conditions Settings Screen will be displayed.
2. Change the settings.
3. Select End.
The settings will be registered and the screen in (1.) will return.

Edge level : [ 10 ]%
Min. level : [ 5 ]
To prevent incorrect detection due to noise (0 to 255).
(If the density variation is less than the minimum value,
it will be considered to be noise.)
Threshold value for finding an edge (0 to 100).
If the measured number of objects is less than
the actual number of objects, set the edge
level (or the minimum level) to a smaller
value.If the measured number of objects is
greater than the actual number of objects,
set the edge level (or the minimum level)
to a larger value.
Edges are detected in the following way:
1. The density differentiation for the entire
measurement range is obtained.
2. The points corresponding to the maximums
and minimums that exceed the edge level
setting are detected as edges.
