Operational Guide 22
DO (Dissolved Oxygen) meter operation is confi gured using the SETUP key with
a DO probe connected to the meter. The parameter-specifi c options will be seen
inserted into the menu.
Parameter Description Choices Default
Altitude (m)
Concentration
measurements of
dissolved oxygen
change depending
on atmospheric
pressure. A
convenient way
to estimate
atmospheric
pressure eff ects
is by the related
parameter of
elevation (m) above
or below sea level.
Enter altitude in
meters closest to
the actual altitude
to ensure the most
accurate calibration

Salinity (g/L)
Dissolved oxygen
solubility decreases
if water contains
salts. Selecting this
factor as to be close
to your known salt
level, will improve
the accuracy of
