J100 Spreader Calibration

1. Importance of Calibration

• Each material requires specific calibration for accurate flow rates during operations.

2. Starting the Calibration Process

• Access the settings tab.

• Select the spreader icon and choose "spreader calibration."

• Click "start calibration."

• Add a new template for the material being used, entering the template name.

• Note: The option for auto calibration is unavailable; proceed with manual calibration.

3. Preparing for Calibration

• Ensure the spreader tank is completely filled with the material.

4. Performing the First Calibration (Minimum Flow Rate)

• Start the first calibration.

• Set calibration time (default is 50 seconds).

• Adjust the spreader opening size to the minimum (10).

• Begin calibration to record weight and dump material.

• Review the recorded weight (e.g., 0.36 pounds).

• Proceed to the second calibration.

5. Performing the Second Calibration (Maximum Flow Rate)

• Set the calibration time to a lower value (e.g., 20 seconds).

• Adjust the spreader opening size to the maximum (100%).

• Start calibration to record data.

• After completion, save the data, establishing both minimum and maximum flow rates.

6. Adjusting Calibration in the Field

• If the spreading rate is inaccurate (e.g., trying to spread 10 pounds per acre but getting a lower rate):

  • Access the template and use the edit button.

  • Select "adjust ratio" to fine-tune the spreading rate.

  • Move the slider to compensate for discrepancies.

  • Confirm adjustments to ensure accurate as-applied data.

7. Conclusion

• Calibration is essential for effective operation of the EA Vision J100 spreader.

• Adjustments can be made easily in the field to maintain accuracy.
