Default Testing a TruTrak Pictorial Turn & Bank indicator on the ground?

Setting the unit on a level table, the 'horizon' matches the wingspan icon. Tilt and hold unit at 45 degrees and the stepper motor adjusts the 'horizon' to match the wingspan icon. Tilt unit back to level and the stepper moves the 'horizon' back to match the wingspan icon. Same for the opposite tilt. (The wingspan icon is fixed on the glass of the instrument. The 'horizon' is rotated by the stepper motor.)


It's a turn gyro, not a horizon reference. Figure it out.
