1 Alignment error is specified as the angle between the true and indicated axis of sensitivity (Figure 1).
2 Cross axis sensitivity is the algebraic sum of the alignment and the inherent sensitivity errors.
3 Defined as the output change from ambient to maximum temperature or ambient to minimum temperature.
