Measured values within
the required precision
If the measured value lies within the range of precision required by the
user, no cleaning or recalibration 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.
Function check in air-
saturated water
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.
