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 tempe-
rature difference, the appliance requires an
‚acclimatisation time' of approx. 15 - 30 minutes
before the measuring procedure can be resumed.
2.0 aPPlIance DescrIPtIon
The CO
value is measured in ppm (parts per million) and
2
is displayed as a digital number on the easily readable
display. There are three different displays:
- 800ppm),
F
(normal) (800 - 1200ppm) und
(>1200ppm).
An acoustic warning is sounded if the measured CO
exceeds a user-specified limit value.
