Basic function principles

Process data output format
In the delivery state, the measured value is displayed in increments of 1/10 °C in two's complement format
(integer). The complete measuring range is output for each resistance sensor. Other presentation types can
be selected via the feature register (e.g., signed amount representation, Siemens output format).
