Ohh ok thanks for that link! So it is non linear. But not even a consistent curve like log, just if less than zero some factor, if positive a different one. Yuck.

I’m more confused about Galen. -4 to 4, 0 is “normal”? 50 c is “normal”? For what??

I have 3 of these and love them. Unfortunately there is a recall on them for mold (never had a problem with mold in my units) and I think because if it, they’re really hard to find now. Amazon has pulled them from sales.

Don’t they make the encoder free, but license the decoder?
