3-18 Relative Scaling Reference Source
Option: Function:
Select a variable value to be added to the fixed value (defined
in par. 3-14
Preset Relative Reference ). The sum of the fixed
and variable values (labelled Y in the illustration below) is mul-
tiplied with the actual reference (labelled X in the illustration
below). This product is then added to the actual reference (X
+X*Y/100) to give the resultant actual reference.
