Procedure for the fertiliser calibration test:
The calibration of the application rate is carried out on
the left hand discharge opening (seen in travel direction).
For this
-
remove left hand spreading disc.
-
Place collecting bucket below the discharge opening
(see ZA-M-Instructions!)
The fertiliser calibration test can be
conducted stationary for the computer only
needs to be informed of the fertiliser volume
per secong passing through the discharge
opening.
-
Start the calibration procedure by pressing
and hold it pressed while pressing
.
The display shows a "0".

-
With the pto engaged, rund the tractor at rated speed
(540 U/min) and open the left hand shutter.
The display now shows the shutter opening time.
-
After at least 30 seconds close the shutter.
After closing the shutter the display changes.

3.1.3.2.4 Fertiliser calibration
The broadcaster can only then be set to
spread accurately when the fertiliser
properties, especially the flowing
behaviour, are exactly known.
This flowing behaviour may already change
after a brief storing of the fertiliser.
For this reason, conduct a fertiliser
calibration test with the fertiliser to be
spread before every operation.
In the event of a drastic change of
application rate for more than 50 % it is
advisable to carry out a fresh fertiliser
calibration.
Preconditions for an accurate calibration are:
•
Before starting the physical calibration process, the
required application rate and working width must
be entered into the computer.
•
An adequate quantity of fertiliser in the hopper.
When calibrating the spread rate entered
into the AMADOS-II may not exceed the
value shown in column "max. spread rate
to be entered for calibrating" in table 3.1 for
the entered working widths.
Table 3.1:
"Max. spread rate to be entered for calibrating for
the entered working width"
