Decode Zones
SE950 Decode Zones
The decode zones for the SE950 scan engines are shown in Figure A-1 and Figure A-3. The figures shown are
typical values. Table A-3 lists the typical distances for selected bar code densities. The minimum element width (or
“symbol density”) is the width in mils of the narrowest element (bar or space) in the symbol.
