Notes

Full Range Output (FRO) is defined as the full acceleration excursion from positive to negative, e.g., ±2g = 4g.
Non-linearity is determined by the method of least squares.
Cross-axis sensitivity is the output of the unit when subjected to full range acceleration in the cross-axis.
Zero offset is specified under certain conditions.
