To achieve the most precise possible dosing result, you should set the mini­
mum fine flow component so that the dosing process is always ended with a
fine flow.
The coarse flow cut-off point cannot be lower than 0, even if you set the mini­
mum fine flow component higher than the fine flow cut-off point. When you en­
ter the target weight, the minimum fine flow component is automatically set to
1% of the target weight if no minimum fine flow component is set.
10.2.22 Lower tolerance (Lower tol.)
This parameter describes the lower tolerance limit for the dosing result. If the
dosing result falls below the tolerance limit, the dosing status is displayed as
“Below tolerance limit”, and the correspondingly configured digital output (Tol.-
or Tol.Error) is set. The status is cleared on the next startup.
When re-dosing is active, re-dosing is automatically carried out if the dosing
result is below the lower tolerance limit. When you enter the target weight, the
lower tolerance limit is automatically set to 99.8% of the target weight if no
lower tolerance is set.
10.2.23 Upper tolerance (Upper tol.)
This parameter describes the upper tolerance limit for the dosing result. If the
dosing result exceeds the tolerance limit, the dosing status is displayed as “Be­
low tolerance limit”, and the correspondingly configured digital output (Tol.+ or
Tol.Error) is set. The status is cleared on the next startup.
When you enter the target weight, the upper tolerance limit is automatically set
to 100.2% of the target weight if no upper tolerance is set.
