Microscan Grading

Microscan Wenglor grading informs the user how the scanner perceives a symbol it is
scanning. Except for special circumstances, the slower the scan speed and the closer
the symbol is to the focal point, the more accurate the results.
The grading feature is available for the following symbologies: Code 39, Codabar, Code
128, I-2/5, and Code 93.
Command Format
<GRADE,xx.xx> where xx.xx is the symbol length in inches with up to two digits in
front of the decimal point and two digits behind the decimal point.
Example: Send <GRADE,01.50> for a symbol 1.5 inches in length.
Operation
Once the command has been sent, the scanner will enter a user test mode for up to two full
seconds. During this time the scanner will attempt to complete ten decodes of the same-
symbol. If this occurs, the scanner will output the grading information for this symbol.
