7.1.1 Measuring D.O.
Selecting the
displayed
measured parameter
You can switch between the following displays with :

D.O. concentration [mg/l]
 D.O. saturation [%]
 D.O. partial pressure [mbar].
Salinity correction When measuring the D.O. concentration of solutions with a salt content of more
than 1 psu, 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 screen.
Air pressure
correction
(Saturation local
function)
The integrated air pressure sensor of the MultiLab 4010-2 measures the
current air pressure.During calibration, the air pressure correction function is
automatically activated. For measurement, the air pressure correction is
applied if the parameter oxygen saturation [%] is displayed and the
Saturation local function is enabled.
1. Connect the IDS D.O. sensor to the meter.
The D.O. measuring screen is displayed.
2. If necessary, select the measured parameter with .
3. Check or calibrate the meter with the sensor.
4. Immerse the D.O. sensor in the test sample.
