Snark SN2

Snark tuner: Red on left- flat. Yellow on right- sharp. Blue bar with dotin center- spot on.
As I tune, left side fills up with red to get the vertical blue bar indicating in tune. Go further, goes to yellow on right.
Confused.

im confused about what you are confused about
the left is red LED and the Right is yellow. color mean nothing. you just want it to have the center green with no Yellow.
Clear as mud?

kind of what I thought. Now clear as cool water.

Thanks
