Do you see fluctuations of O₂ slope negative following a pattern similar to the Peltier power, but without block temperature variation?

Placing the O2k under direct airflow of an air conditioning equipment may lead to disturbances in the O₂ slope negative.

+|'''Do you see fluctuations of O<sub>2</sub> slope negative following a pattern similar to the Peltier power, but without block temperature variation?'''<br>
-The default setting of Slope smoothing is 40 data points, corresponding to an interval of 80 s at a data recording interval of 2 s. DatLab 7 expresses it in data points and DatLab 8 in seconds.
+Placing the O2k under direct airflow of an air conditioning equipment may lead to disturbances in the O<sub>2</sub> slope negative.
