Baseline Calibration.
Note:
Please try not to place your monitor in an environment with a
TVOC concentration higher than 1mg/m
Otherwise, the sensitivity of the TVOC sensor will be reduced
or the TVOC sensor will be damaged.
Manual calibration of the PM2.5/CO
It is recommended to undergo manual calibration performed by a
qualified laboratory every 12 months.
This must be done in a well ventilated room or an environment with
clean air (ideally in a room showing lowest value of CO
PPM, TVOC at 0.2mg/m
Caution : Do not calibrate the monitor in an environment of
