When the upper switchover point (OU) has been fallen below, the next larger available
measuring range is selected. If the lower switchover 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 start of the
measuring range (mba).

Figure 5-32 Define measuring ranges
You can define a maximum of four measuring ranges whose start-of-scale values are
allocated to the bottom value (0/ 2/ 4 mA) and whose full-scale values are allocated to the
top value (20 mA) of the analog output.
If the message "Measuring ranges not plausible!" appears, this means that autoranging is
not possible.
If the start-of-scale and full-scale values are "0", the measuring range is deactivated.
