Selecting the Measurement Mode
Press the Mode key until the icon and measurement unit mg/L
or ppm appears on the display, the meter enters the dissolved oxygen
concentration mode.
Press the key again, the measurement unit will switch to %, the meter
enters the percentage saturation mode.
Dissolved Oxygen Settings
The meter contains 5 dissolved oxygen settings and 7 general settings
in the setup menu.
Calibration Points
Set the number of calibration points.
Pressure Coefficient

the local altitude.
450.0 to 850.0 mmHg, 60.0 to 113.3 kPa
(default 760.0 mmHg, 101.3 kPa)
Salinity Coefficient
Set the salinity compensation coefficient of sample.
0.0 to 50.0 ppt (default 0.0)
Resolution
Set the resolution of the dissolved oxygen
measurement.
0.01 mg/L, 0.1% (default)
Measurement Units
Set the default dissolved oxygen, barometric pressure
and temperature units.
Milligrams per liter (default)
Millimeter of mercury (default)
Degrees Celsius (default)
If you want to change the current settings, press and hold the key
to enter the setup menu. Press the / key to select an option and
press the Enter key to confirm.
Refer to the Setting a Default Option section for detailed
instructions on page 8.
The following table describes the relationship between the altitude
and barometric pressure, make sure to set a compatible parameter
before the calibration and measurement.
Press and hold the / key will make the value change faster.
