The size of aperture to use for grading configured as a percentage of
the nominal narrow element width for the symbol under evaluation.
For example, if you have a 13 mil UPC symbol and you wish to grade
using a 6 mil aperture you would configure the aperture to 46% (6/13 =
0.46).

Any number between 0 to 100%
Overall is calculated in accordance with the ISO 15416 specification.
The overall grade is the average of the individual scan grades applied
to the symbol. The individual scan grades are the lowest individual
parameter grade seen during the individual scan. These individual scan
grades are not available for output.
When enabled, the Overall is attached to the symbol output data as a
value.

Edge Determination is calculated and graded for each scan and pro-
vided for the overall grade calculation in accordance with the ISO
15416 specification. The parameter grade and value provided for out-
put is an average value for each measured scan over the entire symbol.
When enabled, the Edge Determination is attached to the symbol out-
put data as a value.
