Density Defects
CHECK
When the bottom right coordinates are specified, the region will be set,
and the screen in (a) will return.
Use the following procedure to fix the measurement region.
• To measure defects in measurement objects with variable widths only:
Draw the edge detection region so that the measurement region Y co-
ordinates will remain the same for both the upper and lower edges.
The upper and lower edges will always have these edge points.
100,100
Left edge region
100,410
The measurement region will adjust to the right
and left edges only before measurement is performed.
Upper edge region
300,100
300,410
Lower edge region
