The display then changes automatically to
the previous display for a new calibration
sample. When the calibration is complete,
the control system
(fig. 23)
requests the
calibration quantity. The display indicates
merely the
predicted
value for the quantity
of seed released during calibration.
The more accurately that the seed
parameters are entered into the seed
table, the smaller will be the deviation
of the actual calibration results from
the expected value.
Now enter the
measured
value of the
sample weight in kg
(fig. 23)
. If there are
two metering devices, weigh both buckets
together.
Use the numerical pad on the control unit
for this, and accept the displayed value by
pressing
<Enter>
.
There is no need to perform
calculations on the weighed quantity.
Do not forget to enter the decimal
point.
The software only accepts values within
the range of 33% to 300% of the predicted
value.
Otherwise, an error message is displayed,
and a repeat calibration is required!
If the value is unacceptable, it will be
necessary to enter a fictitious value between
33 % and 300%, to be able to repeat
calibration and achieve a successful result.
If the value input is accepted by the
software, the display is as shown in
fig. 24
.
The deviation from the predicted value is
displayed in percent.
The value can be accepted with
<Enter>
,
and the display returns to the warning
display
(fig. 19)
.
It is necessary to check the calibration
procedure, Use the
<P>
and
<S2>
keys to
repeat the procedure as described in 3.2.3.
A repetition is required until the desired
calibration quantity has been reached.
This can usually be achieved within two
repetitions.
The Close Calibration Flap alarm screen
appears until the calibration flap is
closed.
Before starting sowing, close the
calibration flap(s) manually on the
metering housings.
To carry out a further calibration (control)
press the
<ESC> key.
In
fig. 25
the devia-
tion in % is displayed again – confirm this
with
<Enter>
.
