m Moving the appliance from a cold to a warm
environment (and vice versa) can lead to the
formation of condensation on the measuring
circuitry of the appliance. This physical effect,
which cannot be prevented by structural means
for any measuring instrument, leads to false
measurement values. Depending on the tem-
perature difference, the appliance requires an‚
acclimatisation time' of approx. 15 - 30 minutes
before the measuring procedure can be resumed.
2.0 Appliance Description
The CO2 value is measured in ppm (parts per million)
and is displayed as a digital number on the easily read-
able display. There are three different displays:
(0 - 800ppm),
(normal) (800 - 1200ppm) and
(>1200ppm).
An acoustic warning is sounded if the measured CO2
value exceeds a user-specified limit value.
