Overall quality
When selecting result output: "Best read result",
set the comparison criterion. The "Quality" of a
result is evaluated based on the comparison crite-
rion.
Note
Only the selection "Overall quality" is valid for all
code types and verification standards.
If you want to use a different quality criterion,
make sure that this criterion is calculated with the
selected settings. You can find the supported
qualities according to verification standard at
Program format text (Page 76). If a result is com-
pared in processing mode that does not provide
the selected quality, the setting changes to the
overall quality, which can lead to unexpected
results.
