Parameter Descriptions
3-18 Relative Scaling Reference Resource
Option: Function:
variable values (labeled Y in
Illustration 3.24) is multiply by the
actual reference (labeled X in
Illustration 3.24). This product is then
added to the actual reference (X+X*Y/
100) to give the resulting actual
reference.
