The theoretical total of accelerometer output when in a static position is equal to 1 g. However I get a different result depending on where the device is positioned. Some is greated than 1, some is less.

What I have done is determine the max value for each axis and divide all readings of a particular axis by the max for that axis. e.g:

Zmax = 1.14 and so all Z values are divided by 1.14.

I have done this for all three axis but the total is still not equal to 1. If there was a slight offset I could live with this, but it is different for all static positions.

Is there a way of getting the totals being the same for all positions in the 3d plane?

Mark.
