ture displayed.
2. Press the SET button (2) again to have the room demperature


The dew point temperature (also known as dew point) is the
temperature which must be fallen below, given constant pres-
sure, to make water vapor fall out as fog or dew. At the dew point
the relative humidity is 100 % and the air is loaded with water
vapor. The more water vapor the air contains the higher is the
dew point. Therefore the dew point can be used to determine the
absolute humidity.

Usual indoor air commonly perceived as comfortable of 22° C
and 40 % humidity has a dew point of approx. 8° C.

The dew point temperature range of the hygrometer ranges from
0° C to 50° C.

If the dew point temperature is over 50° C "HH.H" will be
displayed, if the temperature is under 0° C "LL.L" will be dis-
played.
