Inspection Tools
7–180
Figure 7.145 (A) appears when the “ Statistics ” option has not been selected
for the corresponding tool, while (B) appears when the “ Statistics ” option
has been selected (and inspection data has been acquired). Note that (B)
applies only to tools for which this option is available.
The Ranges selection panel contains a number of fields, which are
described briefly as follows:
•
Nominal –– The reading in this field is the “nominal” or learned value
that results when you pick the
Nominal field in the Tool Edit panel. It is
included in this panel as a convenience for setting the range limits.
•
Fail High –– Use this field to set the upper “fail” limit.
•
Warn High –– Use this field to set the upper “warning” limit.
•
Warn Low –– Use this field to set the lower “warning” limit.
•
Fail Low –– Use this field to set the lower “fail” limit.
For tools with ranges, the CVIM2 system compares the inspection results
value to the range limits selected for that tool. The tool status is a function of
where an inspection results value lies in relation to the range limits, as
illustrated in Figure 7.146.
