Étalonnage du capteur de CO2 SLPSXC2

ASSSIG-Maroc · ‎2024-09-18

Nous avons installé des capteurs de CO2 SLPSXC2 sur un projet
Suite à la calibration de ceux ci les valeurs remontées de certains capteurs sont incohérentes
Par exemple ceratains capteurs restent à 0 ppm, un autre à une valeur très élevée de plus de 3000 ppm
Est ce que quelqu'un aurait déjà de l'expérience avec ce type de capteur

Hi,

After applying the manual or automatic CO2 calibration process, the CO2 values must stay within range. Seeing steady output of 0 ppm or very high values, such as 3000 ppm, shouldn't happen. If possible, please run the calibration process again, and if issue remains, please contact support team.

Manual calibration: Push and hold the calibration button for 3 to 5 seconds. The LED will flash green. Once the button is released, calibration is complete and the LED switches off.

Automatic calibration: The ABC algorithm constantly keeps track of the sensor’s lowest reading over a preconfigured time interval and slowly corrects for any long-term drift detected as compared to the expected fresh air value of 400 ppm. After initial startup, it is expected that the sensor reaches specified accuracy after 7 to 21 days.
