Inspection Tools
7–56
•
Fail –– This returns an “error code” when the tool is in a fail condition,
and
0.000 for all other conditions. The error code identifies a specific
reason for the failure; for example, error code 1045.000 identifies “High
range fail” as the cause of the inspection failure. The complete list of
error codes and fail conditions appears in Appendix A of this manual.
•
Total –– This returns the total number of inspections performed.
•
Faults –– This returns the total number of faults detected.
•
Fail High –– This returns a 1.000 when the inspection result from the
tool has exceeded the high Fail limit and 0.000 when the result has not
exceeded the high Fail limit.
•
Warn High –– This returns a 1.000 when the inspection result from the
tool has exceeded the high Warn limit (and the tool is not in a fail
condition) and 0.000 when the result has not exceeded the high Warn
limit.
•
Warn Low –– This returns a 1.000 when the inspection result from the
tool has exceeded the low Warn limit and 0.000 when the tool has not
exceeded the low Warn limit.
•
Fail Low –– This returns a 1.000 when the inspection result from the
tool has exceeded the low Fail limit and 0.000 when the result has not
exceeded the low Fail limit.
•
Result –– This returns the actual value of the inspection result; that is, the
count or other numeric result from the window tool. This value
corresponds to the “learned” value that appears in the “
Nominal ” field of
the window tool edit panel.
•
*Height#, Length#, etc. –– Each of these returns a contour measurement
value, which is available only from a window tool configured for black or
white contour operations. Figure 7.48 (page 7–55) shows how the list
appears when all of the contour measurement functions are enabled.
•
**Samples –– This returns the current total number of inspection samples
since the start of run operation.
•
**Min –– This returns the current minimum value of the inspection
results since the start of the run operation.
•
**Max –– This returns the current maximum value of the inspection
results since the start of the run operation.
•
**Sum –– This returns the current sum of all inspection results since the
start of the setup or online run operation.
•
**Sum2 –– This returns the current sum of the squares of all inspection
results since the start of the setup or online run operation.
*Whenever one of these contour measurement functions is selected in a math
tool formula, the “#” sign must be replaced with the appropriate object
number when the “
Single ” operation is selected in the math tool edit panel.
