NOTES
1
Guaranteed by measurement of initial offset and sensitivity.
2
Alignment error is specified as the angle between the true and indicated axis of
sensitivity.
3
Cross axis sensitivity is the algebraic sum of the alignment and the inherent
sensitivity errors.
4
Defined as the output change from ambient to maximum temperature or ambient to
minimum temperature.
5
Output settled to within
±
