Signal quality if no codes were read
If no codes were read, the signal quality is defined as undefined , represented by a signal quality value of 255.
Signal quality of a read code
The values of individual elements of the code quality of a read code are between A (best quality) and F (worst
quality). The total code quality of a read code is defined as the minimum code quality over all individual code
qualities.
Example: Code quality: ADBAADA. Total code quality: D.
If an individual element of the code quality of a read code cannot be determined, the total code quality is defined
as
undefined , represented by a signal quality value of 255.
Signal quality with several read codes
If multiple codes are read in one image, the inspection program pass total code quality over all codes read is
defined as the minimum over all total code qualities.
Example:
Code A, quality: AABC, total code quality: C
Code B, quality: CCDE, total code quality: E
Code C, quality: AAAA, total code quality: A
This results in an inspection program pass total code quality over all codes read of Minimum(C, E, A) = E
If the code quality of a read code is not determinable, the inspection program pass total code quality is defined
as
undefined , represented by a signal quality value of 255.
Mapping of the total code quality to the signal quality
The individual code qualities A, B, C, D, E, F are mapped to integer signal quality values as follows:
Code quality value Signal quality value
A 100%
B 80%
C 60%
D 40%
E 20%
F 0%
