Configuring the job computer
Extremity nozzles
1. - On the work screen, switch the application mode to manual.
2. - Start application
3. and - Set the spray pressure to 3 bar.
4. Using a measuring cup, collect the water from several nozzles for one minute each.
5. Calculate average application rate.
6. - Stop the application.
7. - Activate automatic mode.
8. Switch to the “Calibration” screen:
> >
9. On the “Nozzle” line – select nozzle for calibration. Standard nozzles are referred to by their
colours.
10. In the box below the “New reference point” line, enter the calculated average quantity in l/min.
11. For undefined nozzles, you must also enter the nozzle's minimum output in the “2nd reference
point” parameter. To do so, you must repeat the procedure at a different pressure.
⇨ You have calibrated the selected nozzle.
Extremity nozzles
Extremity nozzles are nozzles with a different spray pattern from the other nozzles on the boom. They
can either restrict the spray width, in which case they are used for spraying field edges (corner
nozzles), or increase the spray width of a section (wide area nozzles).
Before using extremity nozzles, note the following:
▪ Wide area nozzles or corner nozzles can be installed as extremity nozzles. You can choose the
icon used to represent the extremity nozzle on the work screen.
▪ Extremity nozzles can be installed at the outer end of any section.
▪ The width of the spray cone is irrelevant for the ISOBUS job computer. It is never detected and is
not taken into account in the following calculations:
– when calculating the working width,
– when calculating the applied quantity,
– when calculating the tank content.
▪ The TRACK-Leader and SECTION-Control applications from Müller-Elektronik do not take
account of the width of the spray cone from the extremity nozzles; they treat them as normal
nozzles.. If you are using these applications, you may have to adjust the working width manually.
