Table 3-9 shows the representation of the digitized measured value for the
climatic temperature range of the sensor Ni 100 in accordance with
DIN 43760.
The same value range as in the standard range of the Ni 100 sensor applies in
the climatic range Ni 100 only with a higher resolution of 0.01C instead of
0.1 C.

1) The characteristic of the Ni 100 sensor is not defined in the overrange and
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.
