Runout. Runout is a measure of
rotational accuracy expressed by
Total Indicator Reading (T.I.R.). Total
displacement is measured by an
instrument sensing against a moving
surface, or moved with respect
to a fixed surface. A radial runout
measurement includes both roundness
errors and the centering error of the
surface that the instrument head
senses against.
