Connect the polarographic sensor to the RCA / CINCH Temp connectors in the top panel of the device.
It is not necessary connect an external temperature probe, because it is already integrated.

Access this setup menu to select the calibration with Standard (supplied together with the

device in the carrying case) Zero Oxygen (next paragraphs "Calibration").
 Once confirmed the operation, in measure mode on the lower left in the display, the beaker
indicates the point % 0
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.
P5.6 Calibration data O

Access this menu to get information on the last performed calibration. The following screens will
automatically scroll on the display:
First screen: Beakers indicating the points (0% - 100% O

Second screen: OFFSET value of the sensor expressed in %.

 Third screen: EFFICIENCY of the sensor, expressed in Slope %.
 Fourth screen: Value of COMPENSATION of Salinity, expressed in ppt.
Fifth screen: Value of BAROMETRIC PRESSURE, expressed in mbar, at which the calibration was

performed.
 Sixth screen: TEMPERATURE at which the calibration was performed.
Note: The instrument accepts calibrations with Oxygen sensors with Slope % between 80 – 120%.
Outside this range of acceptability, the instrument does not allow to end the calibration and displays the
error message SLOPE OUT OF RANGE. (consult the paragraph 11 Probe Do 7 maintenance)
