Default: Disabled
Options: 0 = Disabled 1 = Enabled
Usage: Sets the threshold for driving the output.
Definition: Conforms to ISO/IEC 15416 symbol quality grading (A,B,C,D).

Default: Grade B
Options: 0 = Grade D
1 = Grade C
2 = Grade B
3 = Grade A
Usage: Lets the user know if symbol quality is less than acceptable.
Definition: If enabled, drives Output if grade is under Contrast Threshold.
