
Code type: Select the type of matrix code in the image.

Detection on teach: Using the Detection on teach option, you can have the code type automatically
determined during external teach.

Parameters: Select the search parameters used to search for the code. Robust, Maximum and User
defined are available. In the Robust or Maximum modes, codes are found even with more
demanding backgrounds. However, this places a burden on the processing time.
In the case of the user-defined search, you can manually set the parameters for the display and the
code.

Optimize on teach: Using the Optimize on teach option, you can have the parameters automatically
adjusted for the code search during the external teach. This is only necessary if you have set the
search parameters in the User-defined option.

Abort read attempt after circa: Use this function to limit computing time for code determination.
NOTE
If computing time for code determination is limited and code quality is also to be
determined, you need to be aware that limiting computing time only applies to code
determination. If necessary, the extra time required for determining code quality should be
established empirically and planned in addition – so deducted from the maximum
permitted computing time, for example.
The limit on computing time may potentially vary between device and PC as they each
have a different computing performance.

Quality: If you also wish to check the code quality, you may activate the Calculate based on ISO/IEC
15415 or Calculate based on AIM DPM-1-2006 option. However, this also increases the processing
time!

Minimum quality: Activate this box if you want to specify a minimum quality.
The code quality is specified as follows:
A - F (A = High quality ; F = Poor quality)
The first parameter corresponds to the overall code quality.
In the ISO/IEC 15415 mode, various characteristics are determined:
o
ECC200 / QR-Code:
Contrast, modulation, pattern damage, decodability, axial non-uniformity (evaluation of width
and height), grid non-uniformity (evaluation of slope angle), unused error correction
