Dissolved oxygen
The general procedures for measuring, calibrating and setting are very similar
with the various types of IDS-D.O. sensors.
Any individual special features of the IDS-D.O. sensors are indicated in the
general procedures.
The individual feature of the
FDO 4410
is, for example, the high stability of its
measuring characteristics during its total lifetime. Therefore, this sensor does
not have to be calibrated regularly. It can simply be checked (FDO Check)
instead.

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 [%]
A sensor with stirrer can only be operated while the meter is line-
powered.
1.
Connect the IDS-D.O. sensor or a D.O. sensor with IDS adapter 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.
Only in special cases does the
FDO 4410
-D.O. sensor require cal-
ibration. Regular checking with the aid of the FDO Check is suffi-
cient.
4.
Immerse the D.O. sensor in the test sample.
