5. If you want to generate quality grades for any of the codes you are reading, you must leave the Enable
Verification Grading check box selected.
6. Enter the Minimum Number of Codes to Train.
7. Click the Train button.
8. For any additional code types you want to train, repeat steps 1 through 7.
Using the Pass Fail Filters
You can define one or more filters to test the characteristics of the defined codes found in the image. If a
code’s characteristics match its enabled filter parameters, that code is read and output. If no filters are
defined or enabled, all the defined codes found in the image are output.
The tool’s pass/fail condition is based on whether the found codes in the image pass all the filter parameters
defined for them. If ALL the enabled filters pass, or no filters are enabled, the codes are considered valid and
the tool passes. If any code does not pass its enabled filter, the tool fails.
The following list inputs are used to define the filters.
Pass Fail Enable: If True, the corresponding filter is enabled. If no filters are defined or enabled, all codes
pass.
Pass Fail Code Type: If this code type is not present in the image, the filter fails.
Pass Fail Match Code: If the decoded string does not match this string, the filter fails. (You can use Wildcard
and Placeholder input properties.)
Pass Fail Min String Length: If the decoded string contains this number of characters or fewer, the filter
fails.
Pass Fail Max String Length: If the decoded string contains more than this number of characters, the filter
fails.
Pass Fail Min Overall Grade: If the Overall Grade for the decoded string is equal to or less than this grade,
the filter fails. The Code Quality Verification input property must be True.
Pass Fail Min Number of Codes: If the image contains this number or fewer codes of the Pass Fail Code
Type, the filter fails.
Pass Fail Max Number of Codes: If the image contains more than this number of codes of the Pass Fail Code
Type, the filter fails.
Wildcard and Placeholder Characters
The Pass Fail Wildcard and Pass Fail Placeholder can be used when you define a Pass Fail Match Code. The
Wildcard matches one or more characters and the Placeholder matches a single character. In the example
below, all codes starting with the characters "AFT" are considered a match, if
• any single character occurs between the "T" and "R" characters (using the "?" Placeholder character)
