ECODE ZONE
The decode zone for the CHS is shown below. The minimum element width (“X Dimension”
or barcode “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 (depths of field)
for selected barcode sizes. The maximum usable length of a barcode symbol (Width of Field)
at any given range is also shown.
