position of the respective sensor code and click on OK.
Changing the Sensor Code, e.g. in case of connecting a new
sensor, requires a new calibration of the oxygen sensor!
Then define the medium of your sample by clicking in the field
Medium and selecting Gas or Water, depending on the
environmental sample under investigation. Then select the
appropriate Oxygen Units for the measurements. Please note that
different oxygen units can be selected for the Medium Gas (%O
2
,
hPa, Torr, dphi) and Water (%air saturation, mL/L, µmol/L, mg/L,
µg/L, hPa, Torr, dphi).
Now the Environmental Conditions in the sample need to be
defined. The possible modes of Temperature Compensation
during
the
oxygen
measurements
include
temperature
measurements in the sample with the connected PT100
temperature Sensor. Alternatively, the measurements can be
performed with a fixed
sample temperature. In
this
case
the
temperature needs to be
measured in the sample
and entered as Fixed
Temperature (°C).
IMPORTANT: For measurements with a Fixed temperature, the
temperature in the sample must be measured and kept constant
during the entire measurement!
For measurements in saline samples (e.g. seawater) using an
oxygen concentration unit like µmol/L or mg/L, the salinity of the
sample must be measured and entered in the field Salinity (psu).
