Seed calibration - metering unit 1
Fertiliser calibration - metering
unit 2
Press key "Calibration metering unit 1".
The menu for turning off the seed is displayed.
The display reminds you about the setting of the
metering unit calibration speed and the filling of
hopper and metering unit.
Calibration speed?
The calibration speed can be selected with the
"Return"-key and set with the + and - keys.
The default setting is 60 revolutions per minute.
This is sufficient under normal conditions.
If work is carried out mainly at high metering
speeds, the calibration speed should be in-
creased to enable almost similar filling of the
metering cells.
Seed calibration
Before starting the seed calibration the setpoints
for seed and metering quantities must be entered
to enable calculation of the working speed.
The metering unit must have the correct rotor
installed.
Rotor selection
The rotor is dependent on seed quantity. working
speed and working width of the drill.
The following tables show the minimum and
maximum seed quantities ate various working
widths and the available rotor sizes for working
speeds of 5, 10 and 15 km/h.
Other rotor sizes for special applications are
available on request.
The setting tables are based on 1 kg/litre With
all types of seeds the specific weight must be
taken into account and according to this, e.g. a
larger rotor must be installed in case of a lower
seed weight.
Entering the setpoint
At "Setpoint" select the metering unit for seed
and fertiliser and enter the required seed or fer-
tiliser quantity in kg/ha with the + and - keys.
