Setting details
Set the detection mode to BRT or DRK (center bright or center dark).
Select the detection direction.
Draw a dotted-line rectangle around the search area.
In order to enhance detection performance, make the Y dimension as
short as possible.
Set the width of the edge (1 to 8) and the flat (1 to 16), as well as the
difference in the light level (0 to 255).
Select whether to employ artifact processing or not.

For more information about artifact processing see page 9·12
"Artifact processing", using shared settings.
When the measurement of lead length item is set to YES, set the
direction in which the measurement will take place.
This will return you to the [MEASURING COND] menu.
