The probe should be perpendicular to shaft centerline for the parallel offset alignment check. Rotate the Ring Hub 360 q while checking the measurements of the probe at each of the 6 wings.

To check the angular offset, adjust the indicator probe to contact the face of the Flex Hub as near to the outside diameter as possible, and rotate the Ring Hub 360 q , checking the readings at a minimum of three wings 120 q apart.
