The parameter
Hysteresis
can be used to prevent fast and unwanted colour
changes. The hysteresis is set in the range 0.1... 10%.
NOTICE
Overlapping colour areas
Note: In the case of large hysteresis values, steps must be taken to ensure that
the ranges of the individual colours do not overlap. Otherwise it is possible that
the colour change may not function in the desired way.
The parameter
Delay
offers a further option to prevent unwanted colour
changes. The colour change here can be delayed between 0…1800 s.
The parameter
Lighting
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, 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". The lighting can be
switched on permanently with the value 0s.
The legibility of the display can be adjusted 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
again.
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.
