Operating instructions, 07/2006, A5E00478463
When the upper switch point (OU) has fallen short, the next greater available measuring
range is selected. If the lower switch point (UU) of the next smaller available measuring
range is exceeded, this is selected.
The UU lies at 10 % (100 % - HystE) of the measuring range. The OU lies at the beginning
of the measuring range (mba).

Figure 5-27 Defining measuring ranges
You can define a maximum for four measuring ranges, the start-of-scale values of which are
allocated to the bottom value (0/ 2/ 4 mA) and the full-scale values of which are allocated to
the top value (20 mA) of the analog output.
If the message "Measuring ranges not plausible!" appears, this means that it isn't possible
for there to be an automatic measuring range switch.
If the start-of-scale and full-scale values are "0", the measuring range is deactivated.
