Aranet4 can be calibrated either automatically or manually at home.
In case of automatic calibration mode, the Aranet4 device needs to be exposed to fresh air at around 420 ppm (for instance, outdoors or in a room with good air exchange) at least once a week.
When doing a manual calibration the Aranet4 device must be exposed to fresh air (about 420 ppm of CO2) and the environment should be stable (not changing) for 30 minutes while the calibration is done. Maintain a distance of at least 1 meter from the device during the calibration process so the CO2 from your breath wouldn’t impede the calibration. To initiate the manual CO2 calibration change the switch position at the back of the device behind the batteries from MANUAL to AUTO and back to MANUAL (maintain maximum of 1 second between each movement). The calibration progress will be displayed on the screen of the device. In case of a calibration failure message, make sure that the environment requirements are met and repeat the process from the beginning.
Manual calibration can be done using the Aranet4 app as well. You can see the instructions of how to do the manual calibration via the app in the Aranet4 Calibration Tutorial.
