5.5.2 Humidity monitoring (for constant climate chambers HPP only)
If humidity monitoring has been triggered,
this is indicated by the humidity display:
the actual humidity is highlighted in red
and a warning symbol
is shown ( Fig.
22 ). If the acoustic alarm has been
activated in the
Sound menu (see page
57), which is indicated by the speaker
symbol
, the alarm is additionally
signalled by an intermittent acoustic
signal. Information on what to do in this
case are provided in the chapter
Malfunctions, warning and error
messages on page 40.
Adjusting humidity monitoring
