Flow Calibration
There are several templates for typical spreading materials in the spreading settings of the DJI
Agras app. Users can start spreading operations directly when using any of the templates. Users
can also create templates if the performance of the templates in the app are not satisfactory or
if other spreading materials are being used. Flow calibration is required when creating a new
template. Refer to the Usage section for more information about creating templates.
• Calibration is required after replacing the hopper gate to ensure the operation accuracy.
Usage
Creating Templates
If the performance of the existing templates are unsatisfactory or other materials are being
used, users can create a new template as follows:
1. Disassemble the spinner disk according to the instructions in the Maintenance section. Make
sure to store the removed pin, nut, and washer carefully.
2. Place the aircraft on a at surface. It is recommended to place a plastic sheet or lm below
the hopper outlet to collect the dispensed material. Add the used material into the spread
tank and close the cover. It is recommended to add more than 15 kg of the material.
3. Make sure the spreading system cable is connected and then power on the remote
controller and aircraft.
4. Go to Operation View in the app, tap , then , and tap Materials Management. Select Add
New Material and then set the type of the hopper outlet in use.
• When using the standard hopper gate that is pre-mounted on with the spreading
system, make sure to set the hopper outlet type to Hopper Outlet 1. When using the
small ow hopper gate that is sold separately, make sure to set the hopper outlet
type to Hopper Outlet 2. Refer to the Replacing Hopper Gate section to learn how to
replace the hopper gate and the recommended materials.
5. Tap Calibrate and the spreading system will start working during the calibration.
6. Set the material amount, spinner disk speed, and ight speed after calibration and tap Save.
7. Power o the aircraft and remount the spinner disk.
