NOTES
1Typical Performance Characteristics.
2Guaranteed by measurement of initial offset and sensitivity.
3Alignment error is specified as the angle between the true and indicated axis of sensitivity (see TPC 15).
4Cross-axis sensitivity is the algebraic sum of the alignment and the inherent sensitivity errors.
5Defined as the output change from ambient to maximum temperature or ambient to minimum temperature.
Specifications subject to change without notice.
