DATALOGIC DS2400
Technical Features -
3.1
3 READING FEATURES
The number of scans performed on the code by the DS2400 and therefore
the decoding capability is influenced by the following parameters:
•
number of scans per second
•
code motion speed
•
label dimensions
•
scan direction with respect to code motion
About 5 scans during the code passage should be allowed to ensure a
successful read.
3.1 STEP-LADDER MODE
If scanning is perpendicular to the code motion direction (Figure 3.1 - "step-
ladder" mode), the number of effective scans performed by the reader is
given by the following formula:
SN = [(LH/LS)
*
SS] – 2
Where: SN = number of effective scans
LH = label height (in mm)
LS = label movement speed
in (mm/s)
SS = number of scans per second
