Frames channel 1 different from the others

With the +10V offset enabled, channels 2-4 seem linear, with 0V ccw, +10V cw and 5V at noon.
My channel 1 is more like : 0V ccw, 1V at noon, 10V cw. Is this a deliberate choice ?

Hi. The curve of each channel is a setting you can change (look in the manual under linear/exponential).

Many merci !

Of nothing :wink:
