3.2.2Picket-Fence Mode
If scanning is parallel to the code motion, the number of effective scans is given by the following formula:
SN =
DS1500
Where: 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 60 mm wide code moving in a point where the reading field is 100
mmwide at a 1500 mm/s speed, the DS1500 (1200 scans per sec.), performs:
