7.3.13. Automatic Free Fall Compensation
Automatic Free Fall CompensationAutomatic Free Fall Compensation
Automatic Free Fall Compensation
The function arranges the free fall parameter using value averaged the last four
weighing values so as to get more precision weighing.
Concerning Parameters of the Function

Advise
When the automatic free fall compensation can not work.
Check the flux of dribble flow.
When the error (| result - final value |) of weighing value is bigger than this
parameter, the function does not work.
Check that dribble flow timer is shorter.
When the timer is shorter than
dribble flow auto-free fall override
time
[5q f-36], the function does not work.
When the accuracy does not improve, even if automatic free fall compensation is
used.
Check the stability of the dribble flow.
When the dribble flow is unstable and dribble flow timer is shorter, the function can
not work correctly.
When the result becomes over, even if automatic free fall compensation is used.
Remove between preliminary and free fall
When the value of preliminary and free fall are near, medium flow only works to
reach to final value and the dribble flow can not work.
