Verification Complete
There is no slider position that is optimal for all specimens, so do not assume that it is best to move
the slider to the green zone regardless of the auto-tuning results. Optimal tuning depends on the
specimen characteristics. Some specimens may perform better if the slider is to the left of the green
zone, and some specimens may perform better if the slider is to the right. If you are unsure about how
system tuning works, do not change the slider settings. In most cases, auto-tuning will provide the best
results for the specimen and you will not have to adjust tuning further.
If the loop is under-tuned, that is, responds in a sluggish manner (also referred to a “tuned cold”), the
indicator will be positioned to the left in the blue zone. In the scope graph, the feedback line (red) will
not respond quickly enough to the command line (blue):
