Detecting Binary Defects
Section 2-12
Measurement Objects with Variable Heights Only
Draw the edge detection region so that the measurement region X coordinates
will remain the same for both the left and right edges. The left and right edges
will always have these edge points.

Changing Detailed Conditions as Required
Change the detailed conditions when the measurement results are unsta-
ble. Change and set the edge level, noise level, noise width, and offset
width as required. (Normally, these four conditions can be left on the de-
fault settings.) After changing the settings, perform an object measurement
to check that measurement can still be performed correctly.
