Overall Grade
This menu item sets the value used by the validator for pass/fail
threshold during the analysis of bar codes. Instead of a letter grade,
numbers are used to allow for more resolution. The numbers can
be translated to letter grades according to the 4.0 grade table
below.
Any bar code with a grade below this threshold value will cause the
printer to display the Overall Grade Fail error message (see “Error
Messages” on page 86) and take the appropriate error action.
Higher values create a stricter pass criterion.
The Overall Grade is determined by taking the lowest grade
obtained for any of these bar code quality parameters:
Decodeability, Percent Decode, Defects, Modulation, EC Min,
Rmin, and Symbol Contrast.
You can set the Overall Grade parameter to a value from 0.5 to 4.0.
The default is 0.5.
