Ensure that the HI 76409 DO probe is
connected to the meter according with the

OPERATING INFORMATION
All parameters are set through the front panel keys and trimmers.
When any key is pressed, the corresponding LED lights up to indicate
that the function is active.
SET POINT
To set the working point of the controller, press the SET key. The display
will indicate the current set value.
Use a small screwdriver to adjust the COARSE and FINE trimmers until
the desired value is displayed in units according with the range selected
(the corresponding % DO or mg/L LED is ON).
The dosing will be active when the DO reading is lower than the set point
(set point + hysteresis overpassed = stop dosing; set point = start
dosing).
SALINITY g/L SET (mg/L range only)
Oxygen measurements can be compensated for salinity concentration and
this correction value can be set by the user.
Select the mg/L mode by using the corresponding switch (rear panel).
