How do I perform a manual calibration?

Due to various effects, e.g. climatic shocks, the sensors in the air-Q can display deviating measured values and the zero line can be shifted. It may also be necessary in special environments (particularly high or low temperatures and temperature jumps) to correct the zero line (offset) of the sensor readings.

The air-Q can usually correct incorrect values automatically over the following days. The prerequisite for this, however, is that the air-Q is in a clean environment, ie. is ventilated regularly. One of the indicators we use here is the VOC value, which must fall below 700 ppb over a minimum period of time. If this cannot be achieved, the automatic calibration is not working well or fast enough.

This can be solved by performing a manual calibration (in the smartphone app under Settings [cogwheel in the app’s dashboard] –> Calibration –> Manual calibration).

If you have a reference measuring device available, enter the measured value in the input field.

Alternatively, if you do not have a reference meter: Ventilate the room thoroughly, close the window and let the air-Q “get used” to the new environment for 10-20 minutes, but temperature is again reasonably stable. Then set the sensor to be recalibrated to “0”.

Please urgently use the latest firmware. This is possible in the app under Settings [cog in the app’s dashboard] –> Update or via this path – Article: “Update Firmware Manually”.
