In batch weighing, the actual Free Fall {Weight at batch finish - (Final weight – Free Fall weight)} is not
equal to the value of the Free Fall setting.
Automatic Free Fall compensation function (Sq F-03) automatically improves the accuracy in weighing
by replacing the Free Fall value with the “moving average of the last four Actual Free Falls” as the next
Free Fall setting
* When the batching error (Net weight at Batch Finish – Final weight) exceeds the Automatic Free
Fall Effective Width (Sq F-04), automatic Free Fall Compensations is not performed, taking it as
an error.
* Since Batch Finish is determined externally in Customer Programmed control weighing, a
calculation is made assuming that weighing is completed when the [F] key is pressed or a control
input signal of Automatic Free Fall command is input.
* This function is not available for a Check Weighing.
* Free Fall setting is updated at Batch Finish.
When a set point is recalled by code, its Free Fall setting can be stored in the memory. (Sq F-29).
It enables recall of an Automatic Free Fall Compensation value of the code.
