Codes for temperature coefficients
The following table lists all temperature coefficients along with their codes for temperature
measurements with the resistance thermometers. You need to enter these codes in byte 4 of
the data records 0, 2, 4, 6 and 8 (see Fig. Structure of data record 0: bytes 0 to 6).

Valid values for fixed reference temperatures
The values that you can set for fixed reference temperatures must be within the nominal
range of the thermocouple used and within the permitted value range. See table below. The
resolution is a tenth of a degree.
