Abstract:
A method and apparatus for calibrating or adjusting an accelerometer, wherein the accelerometer is held stationary to obtain the signal outputs from the accelerometer, representing component vectors making up the composite vector of 1 g. Thus, gain or sensitivity, and the zero-g signal offset along for each axis of the accelerometer is determined and adjustable.
