Overall Grade
ODV-2D > Grading > 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. Higher values create a stricter pass criterion.
The numbers can be translated to letter grades per below:
Letter Grade A = 3.5 to 4.0 range
Letter Grade B = 2.5 to 3.4 range
Letter Grade C = 1.5 to 2.4 range
Letter Grade D = 0.5 to 1.4 range
Letter Grade F = 0.0 to 0.4 range
The Overall Grade is determined by taking the lowest grade obtained for any
of the applicable bar code quality parameters.
See Section “
” for more details.
Minimum
0.0
Maximum
4.0
Factory Default
0.0
IMPORTANT
Any bar code with a grade below this threshold
value will cause the printer to display the Overall
Grade Fail error message (see
) and take the appropriate error
action.
Data Verify
ODV-2D > Grading > Data Verify
This menu chooses whether to compare the data that comes from the vali-
dator is the same as the data that was used to create the barcode from the
emulations.
Disable
The data used by the emulations to create the barcode
is not compared to the data returned from the verifier.
Enable
The data used by the emulations to create the barcode
is compared to the data returned from the verifier. If
there is a mismatch, then the fault
Data Mismatch
will
be declared if the successive retries do not solve the
problem.
Factory Default
Disable
IMPORTANT
The data is only compared when the emulation is
provided the data. Barcodes that are encoded via
graphics do not compare data.
Calculations
The ODV-2D follows the specified algorithm defined in the ANSI X3.182 specification for determining the
Overall Grade based on an average. Although it is not defined, the validator truncates the result of all
analysis parameters averages for a slightly stricter grading.
