10. Calibration
It is recommended to calibrate respectively adjust the sensor annually.
For this please contact the manufacturer. Please check the date of the
last calibration in the attached calibration certificate.
If the instrument has a slight drift due to ageing, temperature or other
effects a dew point and pressure calibration can be performed.
10.1 Dew point calibration
Performing a dew point calibration is critical and the following
considerations should be taken:
•
Perform dew point calibration at the working point. Foe example if
you measure around -40°Ctd do the calibration at that point.
•
Do not perform calibration at too high dew points, as it will cause
big errors at low dew points!
•
We recommend calibration between -40°Ctd and -55°Ctd.
