sensor membrane should be inserted in the memory card slot of the instrument. After the
probe has been connected to the instrument, the instrument should be switched on. When
switching on, the serial number of the new sensor membrane is shown in the display. The
new sensor membrane should then be calibrated. (see "Calibration", section 8)

7.3 Salinity correction

fore, it is necessary to enter the values of the salt content before measuring the oxygen with
such samples so that the salinity correction is automatically carried out during the oxygen
measurement.
