3.3.6 Menu Level Display
The Display menu level is a variable menu whose appearance depends on the
value of the colour parameter. In addition to the various colours for the back-
ground lighting, there are also two auto-functions with colour switching avail-
able.

The mots important parameter is
Colour
. A fixed colour can be defined for the
background colour here. There are also two auto-functions with colour switching
available. Alternatively, the background illumination can be permanently deac-
tivated.
If permanent lighting is not required, the parameter
Lighting time
can be used
to define when the lighting should be switched off after the last time a button is
pressed. In addition to permanent lighting (0 s), automatic shut-down after 10…
600 s is also possible. The set time is only valid if the parameter
Colour
is not
set to "off".
Amongst other things, the legibility of the display depends on the temperature
and the reading angle. To ensure optimised legibility, the display can be adjus-
ted using the parameter
Contrast
. When the contrast is changed, it is possible
that the display appears empty or almost completely black. In this case, the
contrast must be turned up or down.
Via the parameter
Bar chart
, the display can be switched between a display
where the measured value is either shown in large digits or the display shows
small digits and an additional barchart.
Auto1: Colour-change red to green
In the mode with the automatic colour switchover, it is possible to enter the re-
quired switch thresholds "red-green switchover", "green-red switchover".
The switching thresholds can be moved within the measuring range. The series
of switch points cannot be altered.
