Step 5: Customise the CO2 alarm.
The audible alarm is set by default to go off at 1000 ppm.
However, in order to adapt to different needs and regulations, the alarm triggering measure is
customisable. This does not change the measurement system.
In normal display mode, press and hold the "
-
" button (5) until the CO2 value flashes and
the icon appears.
Press the "
+"
and "
-
" buttons to increase or decrease the CO2 alarm threshold value. Press button (3)
to confirm and return to the display.
Caution:
For safety reasons, the alarm threshold for the CO2 concentration level can only be set
between 500 ppm and 3000 ppm.
To activate the CO2 alarm function:
in normal display mode (not including settings), press the "
-"
button briefly and the icon
will appear to the left of the CO2 measurement.
Do this again to deactivate the CO2 alarm.
When the set threshold is exceeded, the alarm sounds and the icon
flashes.
Step 6: Display of the minimum and maximum values.
The Quaelis 14 meter displays the recorded minimum and maximum values for CO2, temperature and
humidity.
In normal display mode, press the "
+"
button on the knob (5)
briefly → the
MAX
symbol (above the
temperature) is displayed as well as all the
MAXI values → press "
+
"
→
MIN
appears (above the
humidity) as well as all the MINI values
→ press "
+
" to return to normal display mode
While viewing the recorded minimum and maximum values, press and hold the "
+"
button (5) to reset.
The display shows "
- - - -
" to confirm.
Attention:
When displaying the minimum and maximum values for CO2, the smiley face does not
appear. This is normal. The meter allows to save the minimum and maximum values for 24H and the
values will be automatically deleted and reset every day at 00:00.
Brightness adjustment :
The Quaelis meter allows you to adjust the brightness on 3 levels: press successively on the button (2)
to increase or decrease the brightness of the screen.
Low battery indicator:
When the battery is low the icon
flashes
and the display shows “
- - - -
“
and the display brightness is automatically reduced.
Calibration function :
Sensors can wear out over time and depending on the level of pollution: measurements and accuracy
can drift. To avoid this problem and to ensure the accuracy of the measurements, the Quaelis 14 meter
has the ABC (Automatic Baseline Calibration) technology which ensures a regular automatic calibration
of the device.
Caution:
The Quaelis 14 is equipped with ABC calibration technology which automatically ensures the
correct functioning of the device.
If the user wishes to perform a manual calibration, it is necessary to ensure that the meter is placed in
a 400 ppm outdoor environment to perform this process. To do this the meter must be in the ON position
and the battery must be fully charged. When not in setup, press and hold the "
+"
button (5), "CAL" will
flash. Press button (3) to start the manual calibration.
Calibration can take up to 30 minutes. Do not turn off the meter or press any buttons during calibration.
When calibration is complete, the display will return to the CO2 measurement.
