4.4.2 Measuring
You can carry out D.O. measurements as follows:
Selecting the
displayed
measured parameter
You can switch between the following displays with <M> :

D.O. concentration [mg/l]

D.O. saturation [%]

D.O. partial pressure [mbar].
Salinity correction When measuring the concentration of solutions with a salt content of
more than 1 g/l, a salinity correction is required. For this, you have to
measure and input the salinity of the measured medium first. When the
salinity correction is switched on, the
[SAL] indicator is displayed in the
measuring window.
Note
You can switch the salinity correction on or off and enter the salinity in
the menu for calibration and measurement settings (see section 4.4.3).
Stability control
(AutoRead)
The stability control function (AutoRead) continually checks the stability
of the measurement signal. The stability has a considerable impact on
the reproducibility of measured values.
The measured parameter flashes on the display

as soon as the measured value is outside the stability range

when the automatic Stability control is switched off.
Irrespective of the setting for automatic Stability control (see page 26)
in the Measurement menu, you can start the Stability control function
manually at any time.
1 Perform the preparatory activities according to section 4.4.1.
