J150 J70 Spreader Calibration

The Spreader Calibration is to ensure accurate material distribution during operation and is vital when spreading product.

How to perform a Spreader calibration on the EAV J150

1. Gather tools and prepare the spreader 0:01

• You only need a pair of pliers for this process.
• Before calibrating, remove the spinner disc underneath the spreader.
• Pull out the locking pin and set it aside.
• Hold the spinner disc with one hand and spin the bottom locking piece to the left to remove it.
• Keep all removed parts together, and do not lose the pin—it prevents the spinner disc from coming off during operation.

2. Set up for calibration and empty the material 1:00

• Place a trash can underneath the spreader because calibration will empty material out.
• If needed, raise the drone using a pallet jack, tractor, or forklift so you can access the underside.
• Make sure you have enough material in the hopper before starting, since the calibration will dispense material during the test.

3. Open the spreader calibration screen 1:29

• From the home screen, go to the flight screen.
• Tap Auto.
• Open the settings in the top-right corner.
• Select Spreader.
• If this is the first time installing the spreader, complete a tank weight calibration while empty first.
• In this example, the tank weight has already been calibrated and the current weight is showing correctly.

4. Create or select a calibration template 1:50

• Add a template for the material you are calibrating.
• Name it something recognizable, like "test".
• Choose the material type based on what you are spreading.
• You can create different templates for different:
  • Seeds
  • Densities
  • Seed sizes

5. Run the minimum flow rate calibration 2:28

• Set the calibration time to 50 seconds.
• Turn the auger speed all the way down to minimum.
• Press Start Calibration.
• Watch for material to begin flowing and for the progress bar to move across the screen.
• Make sure the hopper does not run out of material during the test, or the calibration will not complete properly.

6. Weigh the material dispensed during the minimum test 3:19

• After the calibration finishes, collect the dispensed material.
• Use a secondary scale to weigh it.
• Tare the scale first before weighing.
• Enter the measured amount into the spreader calibration screen.
• Review the displayed values:
  • Starting weight
  • Remaining weight
  • Weight spread
• Tap Next to continue.

7. Reload material and run the maximum flow rate calibration 3:49

• Reload the material you just weighed so the spreader is ready for the next test.
• This step often works best with two people.
• Set the calibration time to the lowest value.
• Set the material amount to 300.
• Run the maximum spreader flow rate calibration.
• Again, make sure the tank does not run out during the test.
• You may need to repeat this process for different material densities or seed sizes.

8. Weigh the material from the maximum test and save the template 4:51

• After the maximum calibration finishes, weigh the dispensed material on a secondary scale.
• Tare the scale before weighing.
• Enter the measured weight into the calibration screen.
• Once complete, the system will show the minimum and maximum spreader flow rates.
• Tap Save or Finish to store the template under the name you chose.
• If needed, you can:
  • Adjust ratios for fine-tuning
  • Delete a failed template
  • Recalibrate if the process did not complete correctly

9. Get help if needed 5:51

• The calibration is now complete.
• If you have questions, contact Agrispray Drones through their website or support channels.

Cautionary Notes

• Ensure that there is sufficient material in the spreader during both calibrations to avoid incomplete calibration.

   

Tips for Efficiency

• Consider having a second person assist during the calibration process for better efficiency.

• Experiment with different densities and seed sizes to find the optimal settings for your specific needs.
