Parameter
Connect the optical sensor to the 6-pole multipin connector.
It is not necessary connect an external temperature probe, because it is already integrated.
Connettere il sensore ottico al connettore di tipo Multipin 6 poli.
Once switched on, the device does not require any polarization time. There, it is ready for use (calibration
and/or measurement).

•
Access this setup menu to select the calibration with Standard (supplied together with the device in the
carrying case) Zero Oxygen (next paragraphs “Calibration”).

P5.2 Salt Compensation (manual)
•
•
The salinity of the sample to be measured influences the partial pressure of the dissolved oxygen.
For a correct measurement, it is necessary to set the salinity value of the sample. If oxygen
measurements are carried out on salt or sea water samples, it is important to modify the
measurement by setting the indicative salinity value of the sample.
•
The default value is 0 ppt, access the parameter
SALT COMPENSATION
P5.2
of the setup menu to
change it and select the desired value between 0.0 … 50ppt.
•
The average salinity of the sea water is 35ppt.
