1. Switch on the Condair Cube: To do this, press the power button inside
the cavity on the lower, left side of the cube (see product overview).
Note:
When the Condair Cube is plugged in via the USB cable, it switches on
2. Place the Condair Cube upright in the room where you want to check
that the sensor on the back of the Cube is reached by the room air and
the excess heat can escape through the ventilation slots.
3. Once the Condair Cube is in place, it requires an adjustment time of ap-
prox. 20 minutes until all values are displayed correctly. In particular, the
the sensor is not yet at operating temperature.

The range "healthy" represents the air quality, which provides increased health
protection and is perceived as pleasant.
The ranges "healthy, "acceptable" and "critical" are distinguished.
The aim is that the current measured value (red point) of the room air is in the inner
green diamond and thus in the "healthy" range.
In the upper area of the view, the currently measured COcontent of the room air
is displayed in a bar view. If the current measured value is outside the green range,
the room should be ventilated to reduce the COcontent in the room.
Note:
If the currently measured value is displayed as a gray dot at the edge of the diagram,
it indicates that the measured value is outside the displayed range.

For every 10 minutes of measurement, a bar is displayed which shows the average
chapter chapter 4.2.1. If the bar is yellow or red, the temperature was too low or
too high on average over the last 10 minutes, taking the health chart into account.
A4-hour chart is available for all measured values of CO, temperature and humidity.
These views are accessible via the arrow keys on the side of the circle.

6. 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.
Important:
Also, if you place the Cube in a new geographical location, it must be recalibrated
for accurate measurement results.
14 Time and date settingCalibration
5.2 Auto calibration
By default, the auto calibration is activated, whereby the sensor calibrates its
value independently. It is important here that the sensor is in operation as
permanently as possible and is exposed to fresh outside air at least once a
week (approx. 10 min).
During auto-calibration, the lowest measured value over one week is taken
as the reference value and recalibrated to 400 ppm.
Note:

3. Enable or disable auto calibration
If the Condair Cube is not operated permanently, it is recommended to deactivate the
auto calibration and to perform a manual calibration when using the Condair Cube.

7.1 SD card
An optional memory card can be integrated via the SD card slot on the right side of
the Cube. If a memory card is detected during the start-up process, the measured
values are saved to the memory card every minute. With the help of Excel, this
data can be displayed and analyzed.
Recommended memory card:
7.2 Power bank
To extend the battery life of the Condair Cube, you can use any power bank with
a 5V USB connection.
7.3 Display on large screen
It is possible to connect the Condair Cube to an external monitor via a PC. To do this,
connect the Condair Cube to the PC via the USB cable and install the necessary
drivers. Then open the Condair CubeTool to start the display on an external monitor.
The values are updated at intervals of 30 seconds.
Note:
The minimum resolution for correct display of the values is 1024x768. Note that
