How can the CO2 monitor
be reset to factory
settings?
Is it possible to
continuously illuminate
the screen of the CO2
meter?
What is a NDIR-sensor?
What does the Automatic
Baseline Correction (ABC)
mean?
To reset the unit to factory settings, hold the ENTER button for
5 seconds until a beep is emitted. The monitor is then reset to
factory settings.
It is not possible to have the screen of the RV2000P constantly lit.
To check whether the CO2 value is too high, use the visual colours
or auditory warning. It is also possible to illuminate the screen by
touching one of the buttons.
NDIR stands for 'non-dispersive infrared'. An NDIR sensor has a
detector that measures how much infrared light of a specific
wavelength is absorbed by the surrounding air. This measurement
is then used to calculate the CO2 concentration.
Automatic Baseline Correction (ABC) means the monitor calibrates
itself to the correct values. When the device is on, it measures the
lowest value over a period of time. This makes the device smarter.
The CO2 monitor also remembers this value if the power is i
nterrupted for a while, so it is not a problem to move the device
indoors, for example.
