When configuring modules the runtime
calibration can be enabled to compensate for
component changes resulting from changes in
the ambient temperature. The update of new
data is delayed by 250 ms during the
calibration interval. A calibration is conducted
at every change of 5
°
C in the ambient
temperature.
