The LS 1220 Wide Angle decodes the symbols as shown in Figure 4-2.. The figures shown
are typical values. Table 4-2 on page 4-6 lists the typical and guaranteed 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. The maximum usable length
of a symbol at any given range is shown below. Calculating The Usable Scan Length
Method on page 2-5.
