CHECKSUM CALCULATION : 
 

CSUM = 0 

– (Sla Fu … + Last_data) 

 

(STX and CSUM are neglected while calculating CSUM) 

 
Example 
 

For Medium (1)  filter:     

@011000220001020001XX    

 
CSUM = 0 

– ( 01+10+00+22+00+01+02+00+01) 

= 0 

– 37 

= C9 

 
Command is @011000220001020001C9 < Carriage Return > 
 
 

5.5  Testing the Scale Performance 

You have to check the scale performance by testing the scale eccentricity, scale 
linearity at loading up to maximum loading value, repeatability etc. before using it.
