Phantom 3 Tutorials- IMU functions, calibration and precautions

This video will introduce the IMU module and show you how to calibrate the IMU. The IMU module is
the aircraft’s sensor and includes a barometer, gyroscope and accelerometer and helps keep the aircraft
steady while in air. The condition of the IMU is crucial for the safety of the aircraft. If you notice that the
camera is not level when mounted to the gimbal or if the DJI Go app displays a bias warning you can
correct this and resume normal operation by calibrating the IMU. How to check and calibrate the IMU.
To prevent the aircraft from overheating during calibration first power off the aircraft remove the
battery and let it cool down for 30 minutes before starting calibration. Calibration should preferably be
done in doors at a room temperature of 20 degrees Celsius to 25 degrees Celsius. Before you begin
calibration make sure that that surface that you place the aircraft on is level. You can use the level
function on your smart phone to check this. Make sure the battery charge is at 50% or above to be able
to complete the full calibration process. Do not touch or move the aircraft while is it being calibrated.
Calibration. Connect the remote controller and mobile device. Power on the remoter controlled and
then the aircraft. Launch the DJI Go app on your mobile device. Tap camera, tap setup in the top corner.
Tap sensor setting, find IMU and calibrate IMU. Check IMU first and see whether any error occurs. Then
tap calibrate IMU. Tap OK. Please wait while the IMU Is being calibrated. The app will notify you when
calibration has been completed. If the calibration fails repeat the above listed steps. If it fails several
times please contact DJI after sales support.
