Dissolved oxygen measurement

• Setting air pressure correction (default: 101.3 kPa)
Because dissolved oxygen is affected by air pressure in the location where
measurement is taking place, you need to correct it at measurement. Set the air
pressure of the location. At sea level, you can use the instrument with the default setting.
If you are using the instrument in a high altitude area, you must set the air pressure
correction.
1. Press the key to enter the setting mode.
2. Press the keys to select "DO" (DO collection setting) and then press the
key.
3. Press the keys to select "PRES KPA" (air pressure collection setting) and
then press the key.
4. Enter the air pressure value of the measurement location and then press the
key.
To return to the measurement mode, press the key.
