11.11.3.1. Reading List
Property
The following settings/results are displayed:
Reading #1 Scanned Code.
Quality If quality grading according to ISO 15416 is activated, the results of qual-
ity testing are displayed at this level. The evaluation of code quality is
specified as a number between 0 and 4, 0 being the worst and 4 the
best evaluation.
Overall Quality
Minimum of all individual grades
Decode
Is set to 4 when the reflectance profile of the symbol
could be decoded according to the reference de-
code algorithm for the symbology and 0, otherwise.
Symbol Contrast
"The range between the minimum and the maxi-
mum value in the reflectance profile. A strong con-
trast results in a good grading"
Minimum
Reflectance
Is set to 4 if the lowest reflectance value in the scan
reflectance profile is lower or equal to 0.5 of the
maximum reflectance value. Otherwise a value of
0 is assigned
Minimum Edge
Contrast
Grades the minimum of the edge contrast values
measured in the reflectance profile
Modulation
Indicates how strong the amplitudes of the bar
code elements are. Big amplitudes make the as-
signment of the elements to bars or spaces more
certain, resulting in a high modulation grade
Defects
Grading of reflectance irregularities found within el-
ements and quiet zones
Decodability
Reflects deviations of the element widths from the
nominal widths defined for the corresponding sym-
bology
Additional
Requirements
Bar code symbology specific requirements: mostly
regarding the required quiet zones, but sometimes
it can be also related to wide/narrow ratio, inter
character gaps, guarding patterns or further sym-
bology specific characteristics
Note: More detailed information regarding the results of quality testing
can be found in the corresponding standard.
Envelope The read code surrounding polygon.
