# step.pid
#
# shows the step function response with a 10%
# step in "manual mode", that is using the
# constant bias parameter only
#
# sets the Set point value the same as the
# desired output, even though it has no
# real effect, so my plot capture routine
# picks it up and it shows in the illustration
