type B:
smr : start of measuring range
emr: end of measuring range
LP: lower changeover point: select
smaller measuring range
UP: upper changeover point: select
larger measuring range
If the upper changeover point (OU) is crossed downwardly, the next largest available measuring range will
be selected. If the lower changeover point (UU) of the next smallest available measuring range is exceeded,
this will be selected.

Operating manual –A5E00222135-01
If the upper changeover point (OU) is crossed, the next largest available
measuring range will be selected. If the lower changeover point (UU) goes below
that of the next smallest available measuring range, this will be selected. The UU
is located at 80% (HystA) of the measuring range. The OU is located at 90%
(HystE) of the measuring range.
The full-scale value must be greater than or equal to the full-scale value
which follows it. Since the measuring spans must at the same time become
larger, the measuring range initial values of the following measuring ranges
must always be smaller.
The following applies to measuring range changeover:
The UU is located at 10% (100% - HystE) of the measuring range.
The OU is located at the start of the measuring range (mba).
A maximum of four measuring ranges can be defined whose initial values
are assigned to the lower value (0/ 2/ 4 mA) and whose final values are
assigned to the upper value (20 mA) of the analog output.
If the message "Measuring ranges implausible" appears, this means that
automatic measuring range changeover is not possible.
If the initial or final value is 0, the measuring range will be switched off.
