Select Linked to Hand / Auto [0] to use the local
reference when in Hand mode; or the remote
reference when in Auto m ode.
Select Remote [1]tousetheremotereference

0.00%
Function:
Define a fixed value (in % ) to be added to the
variable value (defined in par. 3-18 Relative Scaling
Reference S ource). The sum of the fixed and
variable values (labeled Y in the illustration below)
is multiplied with the ac tual reference (labele d
X in the illustration below). This product is then
added to the actual reference ( X+X*Y/1 00 ) to
give the resulting actual refere nce.
