Contrast
The preferred view of
the indication is "from
below", which means,
that the display can be
read best in this view.
The contrast between
the characters and the background is the highest.
Little changes of the view can be evened out by the
contrast setting. The contrast of the indication can be
changed by the user.
Setting range 1 - 12
To get an optimal contrast for the whole temperature
range, the contrast of the indication is self adjusting for
changes of the ambient temperature. This correction is
not indicated in the contrast setting.
