A function check or user calibration can be useful in the following special cases:
 If the measured values appear to be implausible and it is assumed that the
service life of the sensor cap is over
 Routinely within the framework of the company quality assurance
The user calibration takes place in water vapor-saturated air. The suitable con-
ditions are easily provided with the aid of the calibration and storing beaker. For
this purpose, moisten the sponge inside the calibration and storing beaker. Then
insert the sensor in the calibration and storing beaker. The sensor membrane
must be clean and dry for this.
Moisten the sponge in the calibration and storing beaker.
After inserting the sensor, wait for the temperatures of the sensor and storing
cap to adjust.
Note
The steps of the user calibration are described in detail in the operating manual
of the meter.
2.5 Storage
Always store the sensor with the calibration and storage vessel put on at a tem-
perature in the range 0 ... + 50 °C (32 ... 122 °F).
