Functional principle:

Channel 1: Basic measuring range: 0 ... 100 Pa
The measuring range is defined as 10 ... 90 Pa. The green range should be 0
... 60 Pa. Then the critical range (yellow) up to 70 Pa starts. This is where the
red range that ranges up to the measuring range end at 90 Pa starts. The lower
colour changes red-yellow and yellow-green are switched off.

The lower colour changes S1 and S2 are 'switched off' by placing thresholds
outside the measuring range. If the threshold values were to be laid precisely at
the start of the measuring range, the display would shine red in the zero-point,
The cause for this lies in the priority of the colours. The red colour has priority
over the yellow colour and this has priority over the green colour.

This parameter can be used to define an hysteresis for the switch thresholds of
the colour change. The set hysteresis applies to all switch thresholds at the
same time. The input is a pressure value in the current unit. The allowed value
range is stated automatically.
