User Manual For - CONTROLLER/DATA RECORDER MultiCon CMC-N16
◦
Import from template
– copies from internal memory of the device
earlier downloaded user characteristic template. That template is
copied into a logical channel and any changes that are made in this
channel are not effecting the source template,
◦
Export to template
– saves in the internal memory a user
characteristic template from current logical channel under desired
name,
◦
Input unit
– the read only parameter, it displays the unit of the logical
channel source,
◦
Output unit
– the unit of rescaled data,
◦
Num. of point
– the read only parameter, it displays the number of
points that are currently defined in the characteristic,
◦
Edit points
– the submenu that defines a point in the characteristic:
–
Input value
– the point value before scaling,
–
Output value
– the point value after scaling,
–
Add point
button – adds a new point, behind the currently
displayed one,
–
Delete point
button – deletes the currently displayed point,
the parameter is inactive when the number of points in
the characteristic is
2
,
The arrows placed in the upper right corner of the screen allow to
switch between points. The middle button allows a direct selection of
a particular point from the list.
For 2 points the user characteristic works like a linear process (see subsection
b)
).
For more than 2 defined points the user characteristic is a composite of the line
characteristics, therefore for the input value
'x'
the user obtains the output value
'y'
which is described by the relationship:
,where
'slope'
and
'offset'
are the coefficients of a segment contained between two
), and
n = 1, 2 ..
is the number of the segment.
If the input exceeds the extreme
'x'
values of the designated points of
P
n
, the output
value is scaled by the functions defined at the extreme segments.
