Adjustment range of the upper threshold value
The upper threshold value of a switching function can be set in the following
pressure ranges:
Tab. 5-2 Adjustment range of the upper threshold values
This means that the hysteresis amounts to 10 % of the lower threshold value
(logarithmic transmitters) or to 1 % of the full-scale range (linear transmitters)
at least. If another transmitter type is connected to a channel, the respective
threshold values will be adjusted automatically if necessary.
