READING FEATURES

If scanning is perpendicular to the direction of the code movement (Figure 30), the

number of effective scans performed by the reader is given by the following formula:

SN = [(LH/LS)

SS] - 2

These symbols signify:

SN = number of effective scans

LH = label height (in mm)

LS = label movement speed (in mm/s)

SS = number of scans per second

For example, the DS4600A (800 scans/sec.), for a 25 mm high code moving at 1250

mm/s performs:

[(25/1250)

800] - 2 = 14 effective scans.
