Manual
DP (DP = DewPoint): The instrument
can be used in the dewpoint alarm
generator mode by selecting the DP
mode.
The DP mode enables simultaneous display of surface
temperature (e.g. wall) and dewpoint temperature and serves to
trace critical surfaces on which condensation could form by
dropping below the dewpoint.
The dewpoint temperature is the temperature at which air is
saturated with water vapour. On reaching or dropping below this
temperature, for example on cold wall surfaces, condensation
forms.
The surface temperature appears in the upper display and the
dewpoint temperature (TdP) of the respective ambient climate in
the lower display in this mode. No function from the upper menu
can be selected in the DP mode!
In configuration area Unit 1 the unit (°C, °F) to be displayed is set
identically for both temperatures. °C is set at the factory. Both the
surface temperature and the dewpoint temperature (TdP) are
displayed in the selected unit.
The laser light is switched on for measurement location marking as
soon as the DP mode is selected. The laser lights for a maximum
of 2 minutes and can be activated for another 2 minutes
respectively with a
