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
.
