1) The same degree of accuracy as in the rated range is guaranteed in the overrange Pt
100, Pt 200 climatic.
2) The characteristic of the Pt 100, Pt 200 sensor is not defined in the underrange. The
rise of the characteristic curve is retained on leaving the linearized rated range. It is
not possible to specify the accuracy of these ranges.
