Dissolved oxygen measurement

• Setting salinity correction (default: 0.0 PPT)
Because dissolved oxygen is affected by the salinity concentration, you need to correct it
at measurement. Set the salinity concentration of the sample beforehand.
You can select arbitrary numeric value or sea concentration (35.0 PPT). If the measured
target does not contain saline matter, set to 0.0 PPT.
1. Press the key to change the setting mode.
2. Press the keys to select the "SAL" (salinity correction setting) and then
press the key.
3. Select the numeric setting display to set a salinity coefficient, or select "SEA" to
set a sea concentration. And then press the key.
When the numeric setting display is selected, enter the salinity coefficient and press
the
key.
The setting range is 0.0 PPT to 40.0 PPT.
4. Press the key to reflect the change.
