Calibration of TVOC and CO2:
The sensor has an automatic factory calibration and can
therefore be used immediately. This usage variant is
recommended. A manual calibration is also possible.

seconds and then press the "SET” button to confirm the
calibration operation ("CAL" and time display alternately).
The sensor will be calibrated after 2 hours. Please start the
calibration in a non-polluting and ventilated environment.
(Please open your window for ventilation while calibrating)

disconnected during calibration process.
It is recommended to repeat the manual calibration every 1
to 2 weeks.
