OCR Check Digit Modulus

Parameter # 688
This option sets OCR module check digit calculation. The check digit is the last digit (in the right most 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
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
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
