STEP 5: Changing Detailed Conditions
2-17-(9)
Change the detailed conditions when the measurement results are unstable.
Normally, these conditions can be left on the default settings. After changing
the settings, perform an object measurement to check that measurement can
still be performed correctly.

Edge Level
Set a density change level between 0 and 100 that will indicate the edge. Nor-
mally, the default setting of 50% will be fine.
The edge is normally detected as follows:
1.
The density distribution of the whole measurement region is calculated.
2.
The density difference between the lowest and highest density value be-
comes 100%.
3.
The point where the edge level density change is detected becomes the
edge.
