Note: This resolution does not apply to temperature values. The converted
temperature values are the result of a conversion in the analog electronic module
(see Table 12-3).
Note
The following applies to temperature measurements: In the overrange and
underrange, the gradient of the characteristic curve at the point where the
linearized rated range is left is retained.
