Hi sophmatheson,
We checked the issue from customer, regarding this issue, it may be due to sensor-to-sensor deviation, however, the percentage BSEC output is a probability, not the proportion of test gas. You can place the training items and sensors in the same sealed container and try more time to train. If they want, they can use the tested single sensor for training themselves which is worth noting that when using this method, the obtained data can be replaced in the format of the 'datablock', and training algorithm, which can avoid the mistake of sensor-to-sensor deviation.
Refer to the format, you can change all 'sensor index' to 0, and keep 'sensor id' from original, replace some valid output, others like 'Scanning enabled' etc. keep original.
