Barcode quality characteristic display on the user interface
Ten scan lines which return individual results are used to measure the quality of barcode
marking. The overall grade is equivalent to the average quality of all scan lines; please see
Barcode verification (Page 60)
The individual grades displayed on the user interface each represent the average value of
the quality characteristic. However, these average values are calculated solely from scan
lines for which valid quality values could be calculated. For example, even if values can only
be calculated for one of ten scan lines, conclusions can still be drawn on individual quality
characteristics for extremely poor quality codes.
