 The sensors (or box they are mounted in) must be un-mounted so they are not attached to anything. ​ Carefully place the sensors on each of the 6 sides of a box (+- 10 degrees will do) the actual orientation is not critical, so long as enough measurements can be taken to fit a sphere. ​  Leave the sensors in each position for a few seconds. The sensors (or box they are mounted in) must be un-mounted so they are not attached to anything. ​ Carefully place the sensors on each of the 6 sides of a box (+- 10 degrees will do) the actual orientation is not critical, so long as enough measurements can be taken to fit a sphere. ​  Leave the sensors in each position for a few seconds.

 If you use the cheapest sensors, sometimes they have bad accelerometers. ​ Either one axis will always read zero, or they will saturate because the bias is greater than 1g.   This is easy to determine from the accelerometer calibration plot in the pypilot_calibration program. If you use the cheapest sensors, sometimes they have bad accelerometers. ​ Either one axis will always read zero, or they will saturate because the bias is greater than 1g.   This is easy to determine from the accelerometer calibration plot in the pypilot_calibration program.
