What does the inner ring on the side knob "strength fine tuner" do, and how do I use it?Updated 6 months ago

The strength fine tuner is a way for you to fine-tune the grind result to your personal preferences. If you prefer your coffee a bit stronger or weaker, use the Strength Fine Tuner to adjust the grinder to produce more or less coffee than the preset amounts. Turn the strength fine tuner to the right, towards the plus sign (“+”), to increase the coffee amount, or to the left, towards the minus sign (“-”), to decrease it.
