Decode Zones
SE960 Standard Range Laser Decode Zones
Figure A-1 shows the decode zone for the SE960 scan engine. The figures 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.
