· Check your selection by testing the upper and lower limits for the evaluations that you have set.
This can be done using item 9 MAKE A TEST RUN.
· For more information about evaluation conditions, see section 9-2 [3] Evaluation conditions.
[Measurement example]
Line used in
detecting the object
The distance (between the center of 2 adjacent leads)
The center point between edge detection points.
(Detection mode: center (dark))
Lead length (all 5 leads)
The brightness of the
part above the line used
to inspect the object.
These displays can be set using
the up and down keys. (The
choices are NO, Y0 to 7, C000 to
C127)
Items 2 to 4 and 6 to 8 will not be displayed if the setting at items 1 and 5 is REG.NO
(disable registration) on the [MEASURING COND] (mesurement condition) menu.

Set the number of objects (from 0 to 128) that can exist between the edge
detection points and still produce an OK evaluation.
Set the range of distances (from 0 to 702.0) between edge detection points that
will produce an OK evaluation.
· The longest and shortest distances will be displayed in the test results.
Set the range of lead lengths (from 0 to 702.0) that will produce an OK
