Enabled
This will be evaluated against the corresponding threshold to drive the output.
 Defects Threshold
This is to use as a threshold for driving the output. Output will be driven if grade is under the threshold.
 Decodability
Disabled
This will not be evaluated to drive the output.

Grade Metrics
 Overall Grade
The overall is calculated in accordance with the ISO 15416 specification. The overall grade is the
average of the scan grades applied to the symbol. The individual scan grades are the lowest individual
parameter grade seen during the individual scan. These scan grades are not available for output.
 Minimum Reflectance
The Minimum reflectance is calculated and graded for each scan and provided for the overall grade
calculation in accordance with the ISO 15416 specification. The minimum reflectance parameter grade
and value provided for output is an average value for each measured scan over the entire symbol.
 Minimum Edge Contrast
Contrast measurement assume 8 bit 0-255 grey correlate 0-100% reflectance The Minimum Edge
Contrast is calculated and graded for each scan and provided for the overall grade calculation in
accordance with the ISO 15416 specification. The parameter grade and value provided for output is an
average value for each measured scan over the entire symbol.
 Symbol Contrast
Contrast measurements assume 8 bit 0-255 grey correlate to 0-100% reflectance. Contrast is
calculated and graded for each scan and provided for the overall grade calculation in accordance with
the ISO 15416 specification. The parameter grade and value provided for output is an average value for
each measured scan over the entire symbol.
