Measuring D.O.

NOTE
When connecting an grounded PC/printer, measurements cannot be
performed in grounded media as the values would be incorrect.
The USB interface is not galvanically isolated.
1. Connect the D.O. sensor to the meter.
The D.O. measuring screen is displayed.
2. If necessary, select the measured parameter with

4. If necessary, select the measured parameter with
 D.O. concentration [mg/l]
 D.O. saturation [%]
 D.O. partial pressure [mbar].
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.
You can switch the salinity correction on or off and enter the salinity
in the menu for calibration and measurement settings (see section
11.1.5 S
ETTINGS FOR
The stability control function (AutoRead) continually checks the stability of the
measurement signal. The stability has a considerable impact on the reproduc-
ibility of measured values (see section 11.2.3 A
