Code quality

Overview
To check the code quality, you can activate the Code quality function. This function determines the code
quality for bar codes and 2D-codes in compliance with ISO/IEC 15416 and ISO/IEC 15415.
NOTICE
Activating the Code quality function increases the decoding time.
The code quality is given as follows: A ... F
• A = High quality
• F = Low quality
The following options are available:
• Determination of individual features for bar codes and 2D-codes
• Setting of a minimum quality (= NOMINAL MINIMUM)
• Output of each feature via the interface and as a programmable switching output
ISO/IEC 15416 mode: Individual features for bar codes
• Overall quality
• Symbol contrast (SC)
• Modulation (MOD)
• Decodability
• Minimal edge contrast (EC
• Minimal reflectance (R
• Defects
• Decodes
ISO/IEC 15415 mode: Individual features for 2D-codes
• Overall quality
• Symbol contrast (SC)
• Modulation (MOD)
• Decodability
• Fixed pattern damage (FPD)
• Axial non-uniformity (AN)
• Grid non-uniformity (GN)
• Unused error correction (UEC)
• Reflectance margin
