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).
Ensure that the

DO probe is
connected to the meter according with the
colors indicated on the mask.
