. The measuring range is tested on sensing element level. FS = 2g.
4) Includes effects over supply voltage, temperature and life time
6) Sensitivity = {Count(+1g) - Count(-1g)}/2 [Count/g].
7) From straight line through sensitivity calibration (+1g, -1g) points.
8) The cross-axis sensitivity determines how much acceleration, perpendicular to the measuring axis,
couples to the output. The total cross-axis sensitivity is the geometric sum of the sensitivities of
the two axes which are perpendicular to the measuring axis. The angular alignment error
between X, Y and Z axis is included into the cross axis sensitivity.
