I'm trying to understand the basics of why an accelerometer doesn't produce the same result when orientation upside down, compared to being upright.
For example, my circuit board reads between 9.7-9.85. However, when the same axis is inverted upside down, the value can go between 9-10. I'm trying figure out how you can calibrate an accelerometer if an axis produces more of an acceleration when inverted? Surely this should be the same, except the sign being different?
