DS1100
3
For example, the DS1100 (500 scans/sec.) for a 25 mm high code moving at 1000
mm/s, performs:
[(25/1000) * 500] - 2 = 10 scans.

Figure 21 - "Picket-Fence" Scanning Mode
If scanning is parallel to the code motion, (Figure 21), 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, for a 50 mm wide code moving in a point where the reading field is 180
mm wide at a 3000 mm/s speed, the DS1100 (500 scans per sec.), performs:
[((180-50)/3000) * 500] - 2 = 20 scans
