The upper value corresponds to the number of impulses matching the lower value, the measured
distance
If the impulse values for a certain measurement distance is already known, the two values,
measurement distance and matching number of impulses, can be input directly (e.g. change of
tractors in joint use of machines).
If the driving speed has to be calibrated, please proceed as follows:
-
A measurement distance, for example 100 metres, is precisely set.
-
At the start of the measurement distance, press arrow key , the calibration process is started,
a signal sounds.
-
Run along the measurement distance and press the OK key at the end, the measurement
distance flashes.
-
Confirm the measurement distance with the OK key .
If the measurement distance set does not correspond to the lower value in the display, change the
value in the display accordingly.
Note: The calibration run should be done on a field with the spray tank half full. In this way, errors
by slip, subsiding wheels etc. are reduced to a minimum.
§5.11 C
ALIBRATION OF THE DRIVING SPEED
(
WITH RADAR
)
If the driving speed is measured by a radar sensor on the tractor, the calibration is done in Screen
13 .
The number of impulses must be entered manually according to the information in the operating
instructions for the tractor. (basic setting = 130 impulses)
§5.12 C
ALIBRATION OF THE FLOWMETER
Screen 14 contains the calibration of the flow meter.
To calculate the through flow in l/min the spraying computer needs the ratio of numbers of
impulses to litres. The number of impulses per litre is stated on the flow meter.
To calibrate the flow meter, the number of impulses (e.g. 641 pls/l) is to be input in
Screen 12 (as
the bottom value). We recommend checking this value annually (best of all before the spraying
season) by "gauging by litres".
To "gauge by litres" only clear water may be used and the spraying system must be cleaned
thoroughly beforehand (see operating instructions spraying system).
Mode of procedure in "gauging":
-
Fill the sprayer with clear water and set all operating elements to “Spraying” .
-
Switch the power take-off shaft on and allow to run at 540 rpm.
-
On the control box, switch all section switches to “On” .
-
Central switch Spraying to “On” .
