DJI Phantom 3 IMU Calibration Process

IMU calibration.

First thing make sure you remove the gimbal lock.

You need to get the P3 as cold as possible, ideally either place it on the patio at night for 20m or in front of some AC for 10m with the battery out.

The important part is not to turn on the P3 until you are ready with the app as the IMU is heated and the temperature start to rise as soon as you turn the P3 on, for a good calibration the process need to see the widest temperature range it can.

First put the flight mode switch in the middle position P-ATTI mode as this stops the popup menu coming up when you turn the P3 on.

Next open the DJI Go App and turn on the controller, navigate to MC Settings, Sensors and scroll to the bottom and you will see the IMU Calibration button. (P3 still off cooling at this stage) , you will see the IMU calibration button is greyed out,this won't come active until the P3 connects.

Place the P3 on a perfectly level surface and put the battery in and turn on, within a second of the craft connecting to the app the IMU calibration button will be available, press it as soon as you can and allow the calibration to complete, it takes around 10m.

Whilst in progress do not touch the P3 it needs to be completely still no movement or vibrations.

Once complete then perform a Gimbal calibration from the gimbal menu on the same flat surface.

Make sure you perform a Compass Calibration before you fly at the flight location.
