5.3 Calibration assistance
Calibration assistance is a system utility for the seed calibration test.
This function computes the number of crank rotations, showing them on the display, and
also counts the number of crank rotations during the calibration test.
Press the
F
key and use arrow keys
A
or
V
to select calibration assistance<
CAL
>. Press
the F key again to activate the function.
The following choice of surface areas for calibration will now be displayed:
1/10 ha
display <
10
>
1/20 ha
display <
20
>
1/40 ha
display <
4
0
>
1/100 ha
display <
10
0
>
Use arrow keys
A
or
V
to select the size of surface area to be calibrated and confirm the
selection by a short press on the
F
key.
The seed drill monitor will now compute the number of crank rotations and display the
figure. During this operation, values greater than 100 revolutions are displayed as whole
figures. Values under 100 revolutions are shown exactly to the nearest half-turn.
The calibration test can now start. The seed drill monitor will now count the number of
hand crank rotations, starting from the displayed value and running in reverse, thus
providing a constant display of the crank turns that remain to be carried out. The final
five turns of the crank are accompanied by an additional acoustic signal, in order to
warn the operator of the impending end of the calibration procedure. Once the value
reaches zero <0> a constant acoustic signal is activated to warn the operator to stop
calibration immediately.
If calibration does continue, the display will show the corresponding negative value and
the constant acoustic signal will continue to be heard until no more impulses are being
detected at the hectare meter.
To repeat the calibration test: press the
F
key, the calibration test will restart from the
beginning.
To stop the calibration test, press any one of the four green display pushbuttons to
leave this menu.
