3. The Condair Cube displays the exact values of CO2and relative humidity after 3 minutes. However,
it needs an adjustment time of approx. 20 minutes until all values are displayed accurately, especially
the temperature.
4. Calibration: For accurate COmeasurements, the Condair Cube must be calibrated during initial start-up,
Manual Calibration
Place the sensor outdoors, for example outside the window in fresh air.
Menu → Settings → Calibration CO2 → Press “Start”

After approx. 6 minutes – displayed graphically with a bar graph and percentage – the calibration is com-
pleted; the cube automatically switches to the main page.
Important! Check the COvalue. If it is within the range of 400 +/-25 ppm, the calibration was successful.
If the value is above or below this, repeat the calibration!
Auto calibration
This function can be activated via the settings. It’s important here that:
– the sensor is in operation as permanently as possible and
– it is exposed to fresh outside air for approx. 10 minutes at least once a week.
During auto-calibration, the lowest measured value over one week is taken as the reference value and
recalibrated to 400 ppm.
Menu → Settings → Calibration CO2 → Auto calibration → enable or disable
If the Condair Cube is not operated consistently, it is recommended to deactivate the auto calibration and
to perform a manual calibration when using the Condair Cube.
