Percent Decode
You can set how strict the validator grades each bar code. For example,
setting Percent Decode to 60% means that 60% of the scanned bar code
must be readable for the ODV-2D to give the bar code a passing grade. The
higher the percentage value chosen, the stricter the validator grades.

Defects
You can set how strict the validator grades the irregularities such as voids
and spots found within elements and quiet zones for each bar code. For
example, the Defects default is 21%. This means that if the bar code and
quiet zone defects exceed 21%, the ODV-2D gives the bar code a failing
grade. The lower the percentage value chosen, the stricter the ODV-2D
grades.

Modulation

Modulation measures how well the ODV-2D sees the wide elements (bars or
spaces) relative to the narrow elements. This menu item sets the value used
by the ODV-2D for pass/fail threshold during the analysis of bar codes.
Higher values create a stricter criterion for passing.
