If temperature compensation was not specified in the calibration
default settings, enter the temperature of the air-saturated water or
the water vapor-saturated air here manually.
If temperature compensation was specified, the
temperature is determined automatically.

Immerse the sensor in air-saturated water or position it in water va-
por-saturated air (see Chapter 18.2.1 "Calibration methods for O-
DO sensors", page 100). If you use water vapor-saturated air, en-
sure constant air pressure, constant temperature and that no water
drops adhere to the membrane during the calibration procedure.
Wait until the measured value displayed stabilizes and then con-
firm the result of the measurement by pressing "OK".
