This articles describes how and when to calibrate the CO2 sensor of the AirPro and AirPro+ models.
When do I have to Calibrate?
When first receiving your AirPro or AirPro+ sensors, before initial use.
After every impact (i.g. sensor is dropped).
We also recommend to calibrate the CO2 sensor every 2 months. Due to settling of dust particles inside the chamber of the CO2 sensor, you can experience a deviation of readings over time.
Steps:
1. Go to an open field.
2. Remove the top cover.
3. Inside the Remote Node you will find a button on top of the PCB, keep it pressed to start the calibration.
4. Once the calibration has started, you will see that the Remote Node starts blinking with a blue LED. Move away so as not to contaminate the calibration.
5. After one minute the calibration has finished, you can pick up your Remote Node.
