Automatic Free Fall Compensation, Advise | A&D PD4000243 guide

7.3.13.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

Using the automatic free fall compensation

[5q f-20] [1] Average of last four times free fall.

[Function] - [Function setting] - [Sequence] - [Control] - [Free fall compensation]

Using the automatic free fall effective bandwidth

[Function] - [Function setting] - [MatEDIT] - [Code No.] - [AFFC range] Refer to section 6.1.5.Editing Full Parameters of Material Code.

Using the normal free fall

		[5q	f-20]	[0]	No (Not used)
					When using the signal form the I/O terminal to control free fall, use this.
					[Function] - [Function setting] - [Sequence] - [Control] - [Free fall
					compensation]
		Storing the result of the automatic free fall compensation of each material.



		[5q	f- 9]	[1]	Change free fall value
					When using the flash memory, set to [0tHf-11] [2].
					[Function] - [Function setting] - [Sequence] - [Basic] - [Material code, free
					fall value]

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.
