1.4. IMU calibration and settings
IMU calibration is needed very rarely. However,
some things can affect the sensor states: falls and
bumps, temperature changes and long stand by time.
Because of using the additional module upper the shell
of DJI Phantom 4 Pro PPK, the process of IMU
calibration is not the same as the default. To calibrate
IMU you need to do next:
1.
Remove the props from the motors if needed
2.
Remove the gimbal holder and turn on the drone
and the remote controller
3.
Prepare two tables, standing close to each other,
or another flat surface with a hall: the horizon should be aligned with the bubble level
4.
Start the IMU calibration process and make steps 1-5 as they are.
5.
At the step 6 place the drone head over heels. Use the edge of two tables to make this step.
Place your drone like at the photo below
6.
When the step 7 is complete, rotate the drone and place it normally

IMU calibration now is now complete
