7.1.1 Measuring D.O.
Selecting the
displayed
measured parameter
You can switch between the following displays with
<M>
:
D.O. concentration [mg/l]
D.O. saturation [%]
Salinity correction
When measuring the D.O. concentration [mg/l] of solutions with a salt content
of more than 1 psu, 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.

local
function)
The integrated air pressure sensor of the MultiLab 4010-1 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
DO %
Saturation local
function is enabled.
The current air pressure is displayed, when an IDS D.O. sensor is connected.
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
<M>
.
3.
Check or calibrate the meter with the sensor.
4.
Immerse the IDS D.O. sensor in the test sample.
