11.8.1  Belt load factor 1 
The average belt load resulting on the scale from the material test is entered in % of the 
nominal load.  
Observe the percentage belt load during the test in SIWATOOL, on the touch panel or in the 
SIMATIC, and subsequently enter the value. 
11.8.2  Belt load factor 2 
The value to be entered must be larger than belt load factor 1.  
Observe the belt load during the test in SIWATOOL, on the touch panel or in the SIMATIC, 
and enter the value. 
11.8.3  Correction factors 1 and 2 
The correction factors have an effect on the material flow rate display and thus also on the 
totalizer. They are calculated and entered following the material test. The amount recorded 
in totalizer 4 is compared with the actual amount. The ratio between the actual amount and 
the amount in totalizer 4 results in the correction factor. 
Correction factor = (amount of material weighed previously or subsequently) / (amount 
totalized by scale)
