Appendix E Decode Zones
The decode zones for the Class 1 and Class 2 lasers in the In-Hand Scan
Card are shown below. The minimum element width (“X Dimension” or bar
code “size”) is the width in thousandths of an inch (mils) of the narrowest
element (bar or space) in the symbol. The figures shown are the typical
scanning distances for selected bar code sizes. The maximum usable length
of a bar code symbol (Width of Field) at any given range is also shown
