•
Configure scaling
– function, which allows to add a constant value to input
value. It is given by formula:
In this function, there are following parameters:
•
Input unit
– read only parameter, it displays unit of the logical channel
source,
•
Value to add
– it defines offset value,
d)
user char.
- is defined as set of X-Y points. Number of the points is variable and may
be set from 2 to 20 points which make linear segments (see
Fig. 7.34
). After
choosing this option, parameter appears:
•
Configure scaling
– submenu which allows to define further points of the
user characteristic. There are following parameters:
◦
Input unit
– read only parameter, it displays unit of the logical channel
source,
◦
Output unit
– unit of rescaled data,
