calibration procedure #15

Open sawan-flo opened 3 years ago

Hello, When calibrating Accelerometer, it asks for placing it in 6 direction. I know that the 6 directions are for positive and negative X,Y and Z axes but i get a message saying 'an external force might be acting upon it'. What am i doing wrong? Also, what is the particular order for placement in 6 directions? Also i believe, for calibrating Mag, i have to rotate in the 'shape' of 8 or more like in the shape of infinity symbol . Am i correct? And it's my understanding that i should keep the IMU still for Gyro calibration. Is this correct?

It would be really great if you could provide a guide for calibration along with the package.
