Dual-Axis, ovality—measure the difference between two outside diameter measurements (one from each axis).  The two diameter measurements are coplanar and perpendicular to each other.

IMPORTANT:  the orientation of the product radically impacts the accuracy of this measurement.  As shown, the major and minor axes of the product are aligned with the axes of measurement.  In this example, the ovality measurement is accurate.  If the product is rotated 45 degrees, the measurements from both axes will be equal, yielding an ovality of zero—100% error in the measurement!  Solution:  use a Triton™ triple-axis micrometer for accurate ovality measurement regardless of product orientation.
