Hello btruden_henway,
It's the static calibration method. The calibration method is like:
- Enable the virtual sensor: Accelerometer Calibrated and keep reading our the accuracy. The accuracy is 0 at the beginning.
- Put the device on a flat table with the +z axis pointing up. (You can also point other directions up firstly. the key point is to calibrate every direction.)
- After some seconds for step 1, you can then put the +x axis pointing up.
- Repeat the above step 2 and step 3 for other 4 directions: -x, -z, +y, -y.
After a good six-sided calibration described above, the accuracy of the virtual sensor, Accelerometer Calibrated would becomes 3. Otherwise, you have to do the six-sided calibration again, because, maybe you did not put the device on a flat place or the calibration time for each side is too short.
