H-11 ISO/IEC 29158 Symbol Quality
Output 1
Automatic Identification and data capture – Direct Part Mark (DMP) Quality
Supported symbologies:
Minimum Resolution: 6.0 Pixels Per Element
 Output on Overall Grade

Overall Grade Threshold
 Cell Contrast
• Data Matrix ECC200
Usage: Lets the user know if symbol quality is less than acceptable.
Definition: If enabled, drives Output if grade is under Overall Grade Threshold.
