6.9. Auto Free Fall Compensation
Auto Free Fall Compensation adjust the amount of feeded ingredient in “Sequence Mode” to
automatically reduce weighing errors, reaching Final weight as close as possible.
For that procedure
-
AFFC-CN completed cycles are recorded
-
differences (error) between actual weight and Final weight is calculated each time
-
average the errors after AFFC-CN cycles
-
this average is multiplied by CPS-CE for weighting
-
result is added to CPS value.
Example:
AFFC
(3.1.8.4

: ON
Average count of AFFC (AFFC-CN 3.1.8.5 page 45)
