Notes
1. Full Range Output (FRO) is defined as the full acceleration excursion from positive to negative, e.g., ±2g = 4g.
2. Non-linearity is determined by the method of least squares.
3. Cross-axis sensitivity is the output of the unit when subjected to full range acceleration in the cross-axis.
4. Zero offset is specified under static conditions with no vibration inputs.
