OCR Check Digit Modulus
Parameter # F1h B0h
This option sets OCR module check digit calculation. The check digit is the last digit (in the rightmost position) in an
OCR string and improves the accuracy of the collected data. The check digit is the end product of a calculation
made on the incoming data. For check digit calculation, for example Modulus 10, alpha and numeric characters are
assigned numeric weights (see
OCR Check Digit Multiplier on page 14-26 ). The calculation is applied to the
character weights and the resulting check digit is added to the end of the data. If the incoming data does not match
the check digit, the data is considered corrupt.
The selected check digit option does not take effect until you set
OCR Check Digit Validation

To choose the Check Digit Modulus, such as 10 for modulo 10, scan the following bar code, then scan a three-digit
number from 001 to 099 representing the check digit using the numeric keypad in
Chapter 16, Advanced Data
Formatting . The default is
