4.9.1. 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:
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
