Switch on/off
To switch on the meter, press and hold the on/off key for 2 seconds. Make sure you switch on the
meter in fresh air as the meter calibrates itself in the first 90 seconds. This procedure is always
performed when the meter is switched on.
Leave the meter in fresh air for another 5 ... 10 minutes so that it can adapt to the environment.
The temperature and humidity sensors also need 20 ... 30 minutes to adapt to the environment.
To switch off the meter, press the on/off key again for 2 seconds.

soon as the measured value is below >0.09 mg/m³, the backlight turns white again. Even if the
backlight is disabled, the red lighting switches on when the value is exceeded.
