AirMonitor FRESH
Reset
After a holiday and/or an extended period without ventilation, it makes sense
to reset the calibration by pressing the 'Clock button' (a) and the 'Alarm
button' (c) for more than five seconds. This deletes the current calibration
and restarts the calibration process.
Saving the time and calibration values
The time and calibration values are saved for 30 minutes if the device is not
connected to the power supply.
The calibration and time are no longer available if the device is disconnected
from the power supply for more than 30 minutes This results in the sensor
recalibrating and the time must be reset.
VOC and eCO - explanation
2
The VOC content of the air is given in the unit 'parts per billion', abbreviated
to 'ppb'. The measuring device evaluates the VOC content using the official
recommendations of the German Federal Environment Agency as hygienically
harmless or hygienically conspicuous.
The eCO content of the air is given in the unit 'parts per million', abbreviated
2
to 'ppm'. The VOC sensor cannot detect CO directly The eCO value is an
2 2
equivalent concentration of CO which the sensor calculates using other
2
relevant parameters.
