· 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 brightness of the
part above the line used
to inspect the object.
Even if only one measurement of the distance between the center points of 2 adjacent leads (as
shown above) falls outside the range of the upper and lower limits specified, it will result in an NG
evaluation.
Return to the [TYPE00-MEAS1 to 3] menu and select item 8 NUMERIC CALC COND

the [MEASURING COND] 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
evaluation.
