3.7.1. Definition of Sensitivity Error ES
ES is the maximum of the absolute value of 1 minus
the quotient of the normalized measured value¹⁾ over
the normalized ideal linear²⁾ value:
In the example shown in Fig. 3–2 the maximum error
occurs at 10 °C:
ES = max_abs_^{m-i--d--ee---aa---sl} – 1_{}
Tmin, Tmax
ES = ^{1---.--0---0---1-} – 1 = 0.8%
