I was not sure if using 470 ohm resistors instead of the 500-1000ohm was causing it. The bigger question is if I use the Z value since that is the third axis for the conversion then how do I measure acceleration in the z axis? I set the zero offset so that the values all =1. Wouldn't that be sufficient to measure G's since a value of 1 should equal 1 G? I guess I am trying to see if the conversion factor is a constant that can be hard coded or dynamic based off the other axis?
