Function channels
At the end of the table of measuring ranges and units (see above) under the
sub-heading
function channels
there is a group of ranges that can be used to
represent function parameters for measured value processing or for calculated
results obtained by linking certain measured values on measuring channels
(see Manual 6.3.4). Reference to the actual measuring channels is provided by
one or two reference channels. For all function channels there are preferred
channels on the appropriate connector; reference channel programming is not
required because these values are referred to by standard reference channels
Mb1 and Mb2.

Arrangement of channels on the connectors
Once the range has been programmed the standard reference channels can be
used. Settings for the reference channels are described in Section 13.12.6.
