11.4.6  Resolution of flow rate 
The resolution for the material flow rate and totalizers 2 to 6 can be defined in accordance 
with the standard EN 45501 (1*10**k, 2*10**k, 5*10**k]; k: -3 … 2)  from 0.0001 to 50. 
Note 
If the jumper is closed to protect data with verification capability, the parameter can no longer 
be changed. 
11.4.7  Resolution of master totalizer 
The resolution for the master totalizer (cannot be deleted) can be defined in accordance with 
the standard EN 45501 (1*10**k, 2*10**k, 5*10**k]; k: -3 … 2)  from 0.0001 to 50. 
Note 
If the jumper is closed to protect data with verification capability, the parameter can no longer 
be changed. 
11.4.8  Design flow rate 
The design flow rate is entered during initial commissioning. It can be obtained from the data 
sheet for the belt scale. It corresponds to the maximum material flow rate (100%) for which 
the conveyor belt is designed. 
The % values for the material flow rate limits refer to the rated flow rate. 
11.4.9  Weigh length 
In the case of a scale with a roller station, the weigh length corresponds to half the distance 
from the roller station to the adjacent rollers on the left and right which are located upstream 
and downstream of the roller station. 
With two or more roller stations, the distance between the roller stations is added to this. 
Note 
If the jumper is closed to protect data with verification capability, the parameter can no longer 
be changed.
