Measured values within
the required precision
If the measured value lies within the range of precision required by the
user, no cleaning or recalibrating is necessary.
Example:
Required precision 5 %.
Measured value in air: 97 % saturation (nominal value: 100%)
 No cleaning or recalibration is necessary as the measurement error
lies within the range of precision required by the user.
Measured values
outside the required
precision
If the measured value lies outside the range of precision required by the
user, clean the sensor shaft and membrane (see section 5.2) and
calibrate the sensor (see section 4.2).
Note
In the case of air temperatures under 5 °C do not perform the function
check in air but in air-saturated water that has a higher temperature.
You obtain air-saturated water by pouring water several times in and
out of two vessels so that it sparkles.
Then submerse the sensor in a vessel with air-saturated water and
perform the function check as described above.
