Datalogic Scanning DS4300 manual Picket Fence Mode, Sn = Fw-Lw/Ls * Ss

DS4300 DATALOGIC

For example, the DS4300 (800 scans/sec.), for a 25 mm high code moving at 1250 mm/s performs:

[(25/1250) * 800] - 2 = 14 effective scans.

Figure 3.6 - "Picket Fence" scanning mode

If scanning is parallel to the code motion, (Figure 3.6 - "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, for a 100 mm wide code moving in a point where the reading field is 200 mm wide at a 2000 mm/s speed, the DS4300 (800 scans per sec.), performs:

[((200-100)/2000) * 800] - 2 = 38 scans
