Calibration of the Oxygen measurement
The Oxygen measurement is calibrated in water-saturated air.
1) Switch off the controller. Take the sensor out of the armature, dry the sensor tip carefully with a napkin,
hold it in the air above water with the membrane pointing down and wait until the reading is stable.
2) Calibrate by pressing key
3) Check the displayed slope, put the sensor back in the armature, wait until the reading is stable, then
switch the controller on again.
NOTE
The Oxygen measurement strongly depends on temperature. Make sure that automatic calibration is
selected during calibration.

Select between two ways of compensation:
1)
Automatic compensation
with temperature sensor
Mind that the temperature sensor should always measure the temperature around the conductivity sensor.
When conductivity sensor and temperature sensor are not immersed in the same solution, better switch to
manual compensation.
2)
Manual compensation
If the temperature can be regarded as constant, you can enter the temperature manually instead of
measuring it continuously. The device will then compensate the temperature error of this temperature.
4.3.1
Calibration of the temperature measurement
When using a 2-wire connection for the temperature sensor, please check the temperature measurement in
the beginning. If the displayed temperature differs from the real temperature, enter the deviation as
correction in the basic settings. This correction will be added to all temperature measurements. If your
calibration was correct, the temperature displayed is now equal to the real temperature.
