11 Indicator scale for particle
contamination
Colour indicator for the
degree of particle
contamination (For an
explanation of the colours
please refer to chapter
Operation.)
12 Measured relative humidity
value
13 Measured ambient
temperature value
14 Air quality assessment Levels: good, normal, poor
15 Measurement status
: Device performs
particle measurement
(interval between
measurements can be set
in minutes: 5, 10, 15, 30,
60, OFF). If the
measurement interval is set
to OFF, the device performs
a non-stop particle
measurement.
: Device is presently not
performing a particle
measurement.
Regardless of the status of
the particle measurement
the device permanently
measures relative humidity,
ambient temperature and
carbon dioxide
concentration.
