(This item pertains to the check boxes on the General tab of the Setup Options dialog box. You can open it through the F5 key or through the Edit | Preferences | Setup menu option.)
The Use Find Nominals Override for Scans check box allows you to override found nominals when searching for nominal values for a scan's measured points when it executes.
The execution must fail to find at least one of the measured nominal point values for you to override the found nominals.
See "Overriding Found Nominals" in the "Editing a Measurement Routine" chapter.
