When the upper switchover point (OU) is fallen below, the next larger measuring range
available is selected. If the lower switchover point (UU) of the next smaller measuring range
available is exceeded, this measuring range is selected.
The UU lies at 10% (100% - HystE) of the measuring range. The OU lies at the start of the
measuring range (mba).
8.4.3 Define measuring ranges (function 41)
Figure 8-23 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.
