If, due to a fault (e.g. tank empty) the pre-set rate is not achieved, an alarm is set off.
Input value

The value entered is controlled by pressing again.
6.2.5 "Impulses / litre" key
Direct input of impulses per litre or a calibration of the flow meter can be carried out here. The various possibilities are
described in the chapters 6.2.5.1 - 6.2.5.3.
6.2.5.1 Impulses per litre input
If the number of flow meter impulses per litre is known, the value can be entered directly.
1. The value impulses/litre is known:
> Press
> Enter the value using the keys and
> Press to transfer the new value
6.2.5.2 Tank method
With the tank method calibration is carried out by weighing the entire field sprayer before and after spraying. The procedure
is as follows:
> Fill the tank with water and determine the quantity (weigh).
> Press and simultaneously
> While stationary, switch on the field sprayer using and spray a few hundred litres.
(The computer now counts the flow meter impulses). All sections must be open.
> Switch off the sprayer using
> Determine the amount sprayed (reweigh).
> Set the value using the keys and
> Press to transfer the new value
> The computer calculates the "impulses / litres"
The flow meter impulse number should be checked several times a year especially before each season.
6.2.5.3 Nozzle method
With the nozzle method the quantity sprayed is measured at a nozzle and projected to the total number of nozzles. The
procedure is as follows:
> Fill the tank with water.
> Secure a measuring jug below a nozzle.
