That would be UP in my case then.
What does this switch actualy do?
I see a change in freq when I switch up or down.

I'll put then a reference signal of 440 Hz on my A-channel of the scope and the the B-channel will be connected to TP1 then.
The Polysix is warming up now, and later I'll try to calibrate again.

I will post the result.
