The power of this function is that before the combination
(operative) each of the two inputs can be weighted with a factor
and the combination result can be set with a further offset.
What is important is that all values are entered in engineering
units.
Additionally the calculated value can be linearised over a max.
20 points using a third linearisation table. For this the setting
MCURV must be set to TABLE. The first and last points in the
table must be set to the following settings.
Enter of further points is done in
TAB M under NOM02, NOM03 etc.
(see linearisation table).
The linearisation value can also be moved using the setting
MDIOF.
