Rmin
NOTE: This parameter factors into the Overall Grade (page 57).
This menu item sets the minimum reflectance value used by the
validator for pass/fail threshold used during the analysis of bar
codes. A bar code will fail if all the bar reflectance values are above
the percentage of space reflectance set by this threshold. For
example, an Rmin setting of 50% requires that at least one bar
reflectance value fall under the mid point of the reflectance value
read for the highest space reflectance.
You can set the Rmin parameter to a percentage value from 0% to
100%. The default is 50%.
