Generate intermediate values : When enabled, results are also output between
reset events immediately following their calculation, (without being reset to zero).
4.7.9 Channel group
Use channel groups to group related or interdependent channels. Any number of
channel groups may be created. If required, a channel can be linked to more than
one group (linked channels: refer to
Configuring software channels).
4.7.10 Linearisation
Linearisation enables an additional conversion to be performed on a channel's val-
ues. An advantage of this feature is that the channel's original values remain avail-
able with the conversion being performed in a "new" channel.
The available options are identical to those for a global table. This dialogue enables
either a conversion function to be set for this channel (
Table type: local table ) or
the use of a global linearisation function ( Global table ) which has been set up via
the Global linearisation table option in the device's context menu.

Table tab).
A table can be imported instead of creating a new one: Import .
Mode : There is a choice of modes
l
Offset
An offset shifts the curve by a fixed value, for example the given value is
added to the measurement value.
l
Offset and slope
Allows a shifting of the curve and an increase in its slope.
l
Quadratic
Generates a quadratic curve through the given points to linearise the meas-
ured values.
l
Linear interpolation
Set a table for converting measured values into display values. Linear inter-
polation takes place between the given points.
l
Spline interpolation
