Advanced Validator Options
Modulation
NOTE: This parameter factors into the Overall Grade (page 57).
Modulation measures how well the scan laser sees the wide elements (bars or spaces) relative to the narrow elements. In general, scanning lasers see bars better than spaces and wide elements better than the narrow elements. This menu item sets the value used by the validator for pass/fail threshold during the analysis of bar codes. Higher values create a stricter criterion for passing.
You can set the Modulation parameter to a percentage value from 0% to 100%. The default is 50%.

EC Min
NOTE: This parameter factors into the Overall Grade (page 57). The higher the value, the stricter the criterion for passing.
This menu item sets the minimum edge contrast, which is the worst edge transition (bar to space or space to bar) used by the validator for pass/fail threshold during the analysis of bar codes. Bar codes with an edge contrast below this threshold will fail.
You can set the EC Min parameter to a percentage value from 0% to 100%. The default is 15%.
