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.
