Selecting the
displayed
measured parameter
You can switch between the following displays with
<MODE>
:
 D.O. concentration [mg/l]
 D.O. saturation [%]
 D.O. partial pressure [mbar].
Salinity correction When measuring the D.O. concentration [mg/l] of solutions with a salt content
of more than 1 g/l , a salinity correction is required. For this, you have to mea-
sure and input the salinity of the measured medium first.
When the salinity correction is switched on, the [Sal] indicator is displayed in
the measuring screen.
1. Connect the D.O. sensor to the meter.
The D.O. measuring screen is displayed.
2. If necessary, select the measured parameter with
<MODE>
.
3. Check or calibrate the meter with the sensor.
4. Immerse the D.O. sensor in the test sample.
