4.14.1. Definition of Sensitivity Error ES

ES is the maximum of the absolute value of the quo-

tient of the normalized measured value1) over the nor-

malized ideal linear2) value minus 1:

In the below example, the maximum error occurs at

10 °C:

Fig. 4–6: ES definition example

1) normalized to achieve a least-squares method

straight line that has a value of 1 at 25 °C

2) normalized to achieve a value of 1 at 25 °C
