Hi,

As per the internal team, the FCS scheme now lets you calibrate the sensor up to 1500 ppm for the final sample. So, now you can provide the calibration value of 1000 ppm as per your setup.

Thanks

If possible you may need to think of using FCS scheme time to time. However at this point of time, the FCS is capped at 900 ppm unfortunately. So, even if you try to input 1000 ppm, it will cap it to 900 ppm. In the future if the upper cap can be increased to bigger value I will update with new information

Hi,

In your case, the CO2 concentration is not changing. For such cases, you can use the FCS scheme (Forced Compensation Scheme) which lets you calibrate the sensor to a fixed concentration of CO2. Yes, the upper limit for this scheme is set to 900 ppm but I'm following up on this request with the internal team and we need some more time. I'll revert back to you on this asap.

Thanks
