Figure 3.2 - "Picket-Fence" scanning mode
If scanning is parallel to the code motion, (Figure 3.2 – Picket-Fence mode),
the number of effective scans is given by:
SN = [((FW-LW)/LS) * SS] -2 These symbols signify:
SN = number of effective scans
FW = reading field width (in mm)
LW = label width (in mm)
LS = label movement speed (in mm/s)
SS = scans per second
For example, the LS2200 running at 1000 scans/s., reading a 50 mm wide
code moving through the point where the reading field is 100 mm wide, at a
speed of 2000 mm/s, performs:
[(100-50/2000) * 1000] - 2 = 23 effective scans.
