Calibration / Adjustment
Recommendations for Calibration
It is always recommended to calibrate in air. Compared to water, air is a cal-
ibration medium which is easy to handle, stable, and thus safe. In the most
cases, however, the sensor must be removed for a calibration in air. In certain
processes the sensor cannot be removed for calibration. Here, calibration must
be performed directly in the process medium (e.g. by means of a product
calibration).
If there is a temperature difference between the calibration medium and
the measured medium, you must keep the sensor in the respective medium
for several minutes before and after calibration in order to achieve stable
measured values. The type of calibration pressure detection is preset during
parameter setting.
