The blue indicator shows the eccentricity of the large cylindrical surface to the shaft centerline E = (E1 – E2)/2.
E1 and E2 are max and min values shown by the indicator.
The pink indicator shows the error in perpendicularity of the large face to the shaft centerline P = (E1-E2)/2A.
E1 and E2 are max and min values shown by the indicator.
A: distance between measuring point and the shaft centerline.
