Datalogic Scanning DS4600A ユーザーズマニュアル

DS4600A 

If scanning is perpendicular to the direction of the code movement (Figure 31), the 
number of effective scans performed by the reader is given by the following formula: 

 

 

 

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.
