Measuring

The following parameters can be measured:
l

Oxygen concentration

l Oxygen saturation
l Oxygen partial pressure
The dissolved oxygen meter has the following functions:
l AutoRange (automatic selection of the measuring range),
l AutoRead (drift control) to check the stability of the
measuring signal. This ensures the reproducibility of the
measuring signal. How to switch the AutoRead function
on/off see page 93.
Caution
When connecting an earthed PC/printer, measurements
cannot be performed in earthed media as incorrect values
would result.
The RS232 interface is not galvanically isolated.
4.2.1 Oxygen concentration
When measuring the concentration in test samples with a
salt content of more than 1 g/l, a salinity correction is
required.
Note
How to enter the current salt content is described in on page
100. How to switch the salinity correction on/off see below.
