Note
Requirement for optimum code quality
The code qualities are only output correctly when a program is set with the "Read code" task
with calibrated or uncalibrated verification according to ISO
16022. Otherwise, the quality
codes are not calculated when the code is read and ca
nnot be output.
In the WBM, use the definition of the format string "Format text" under "Program > Result >
Program format text" to output the quality values for other selected verification types. The
quality values are then output according to the paramet
er settings along with the read result.
