Checking the application rate

Interval

  • all 1000 Operating hours

    or

    Every 12 months

The actual application rate is checked at a standstill through the individual nozzle output.

To do so, at least one nozzle must be used both on the left and right boom section, and also in the middle of the sprayer boom.

 
Equipment for checking:
1

Quick-check cup

2

Stopwatch

  1. Enter the application rate in the Main menu on the ISOBUS control terminal.
  2. Enter the simulated speed in the Setting menu on the ISOBUS control terminal.
  3. Fill the spray liquid tank with 1.000l of water.
  4. Switch on the agitator on the TwinTerminal.
  5. Start the spraying procedure on the ISOBUS control terminal.
  6. Check all of the nozzles for proper flow.

  7. To determine the individual nozzle output on multiple nozzles:

    Hold the quick-check cup for exactly 30 seconds under each nozzle.
  8. Stop the spraying procedure on the ISOBUS control terminal.
  9. In the Setting menu on the ISOBUS control terminal, set the simulated speed to 0km/h.
  10. Convert the average individual nozzle output to one minute.

  1. To determine the application rate in l/ha:

    Read the value from the table on the quick-check cup

or

Calculate the value.

 
Table on the quick-check cup
1

Determined application rate: 290l/ha

2

Determined spray pressure: 1,6bar

 
Formula for calculating the application rate
A

Application rate in l/ha

D

Average value for nozzle output in rpm

F

Forward speed in km/h

  1. If the values determined for the application rate do not match the set values:

    Calibrate the flow meter, see ISOBUS software operating manual, section Calibrating the flow meter.

or

Check all nozzles for wear and blockage.
