Auto free fall compensation adjusts the amount of suspended ingredient automatically to reduce
weight error. Register auto free fall compensation parameter.
Principle of auto free fall compensation
Sampling the weight value when the complete signal turns ON after Set Point 3 finished.
Record “n” times(A) the difference(D) between set Final value and actual weight value, average the
difference and multiplied by compensation coefficient, then add the result of Compensation value.
F701-C can regulate the value of D for minimizing the errors.
When D is within the range of (Final + AFFC.) ≧ Actual weight ≧ (Final - AFFC.), F701-C
processes auto free fall compensation.
And when compensation feeding is ON in Sequence Mode, F701-C samples the weight value
before compensation feeding.

Value added to Compensation value
The auto free fall compensation function stores compensation samples by
using the Over/Under judgment signals.
If the number of Judging Times is set to 00 (no judgment), the F701-C cannot
store such samples for auto free fall compensation, so that the compensation
function does not work.
For using the auto free fall compensation function, set the number of Judging
Times to 01 or more.
For details, please refer to "a) Judging Times" on P.96.
