Slip/ skid (ball) centered adjustment

[chriscobb1]

To get the ball centered I have to horizontally rotate the ADAHRS about 10 degrees from a straight forward position.  Is there a calibration or I have I done something wrong?

UPDATE
Dynon Tech Support suggested that I laterally level the ADAHRS. It took a very small shim and the ball is centered.

This is strange that there is no offset cal. On mine, the ball is touching the left edge of the. I have a dual ADHRS system. If I shim up one unit, what about the other unit?

Thanks.

They should match if they're mounted together. But they do have their own independent sensors and attitude solutions is the bottom line. You can select which one is active by going to SETUP MENU > PDF SETUP > ADAHRS SOURCE SELECTION to see what each of their attitudes looks like. Basically, they both need to be individually leveled.
