ISO Parameter Grade Thresholds

ISO parameter fail thresholds are set in the SV Series by commands requiring
numeric settings that correlate to the parameter calculations. Following are
descriptions of how the numeric calculations are divided into letter grades per the
ISO Bar Code Quality Specification.

Conversion of letter scan grade to numeric grade

A=4, B=3, C=2, D=1, F=0

Conversion of numeric symbol grade to letter symbol grade (used in aver-
aging)

3.5 < A < 4.0
