Nozzle assistant
 
The nozzle assistant serves the following purposes:
▪
To show how the nozzle type affects the possible application rates and speeds.
▪
To help with the correct selection of the installed nozzle type.
▪
To change the target rate.

 Düsenassistent 1
Determination of possible application rates
Selected nozzle
Here, you can enter:
- The intended working speed
- The optimal pressure for the nozzle
Here, you can see which application rates are possible with this nozzle at the set working speed.
 Düsenassistent 2
Determination of the fitting nozzles
Selected nozzle
Here, you can enter:
- The intended application rate This is adopted directly from the "Rate" parameter.
- The optimal pressure for the nozzle
Here, you can see the speed at which this application rate can be reached.
 
 
 
Procedure
 
 
 
To calculate the application rate that can be reached with a nozzle at a given pressure:
1.
Switch to the "NOZZLE ASSISTANT" screen:
 FS_JR3_Einstellungn-Menü >  FS_JR3_Düsen Assistent
2.
 FS_JR3_Taschenrechner wechseln - Press for the  Geschwindigkeit speed icon to appear in the "User data" area.
3.
Select the box with the nozzle colour to select a nozzle.
⇨
The list contains all standard nozzles and four positions for the configuration of custom nozzles.
4.
Enter the intended working speed in the  Geschwindigkeit box.
5.
In the  SY_JR3_Druckbereich area, set the optimal pressure range that enables the intended drop size with the selected nozzle. This value can be found on the nozzle data sheet.
⇨
Note: The pressure range set here will not be adopted for the application. During operation, you must ensure for yourself that the sprayer is working in the intended pressure range.
⇨
In the "Results" area, the possible application rates appear.
If the calculated application rate is too high or too low:
▪
Change the working speed.
▪
Install different nozzles. Perform the calculation for the new nozzle colour.
 
 
 
Procedure
 
 
 
The calculation can be performed based on the intended application rate:
1.
 FS_JR3_Taschenrechner wechseln - Press for the  Istwert icon to appear in the "User data" area.
2.
Enter the intended application rate in the  Istwert field.
3.
Enter the pressure range for the nozzle colour.
4.
In the "Results" area, you can see the speed at which the application rate can be achieved.
