Gain identification value for the
process. This value is used to
estimate the size of the initial output
step for a SP Tune.
This defines the value of the initial
output step change that is used as
the target for process identification.
Range is 0.10 to 10.0
Normal value is 1.
Range is: 5 to 15
percent.
