A system and method for measuring the radial runout of a shaft, rotatably supported on a standard rest, includes at least a first journal surface sensing assembly, a second journal surface sensing assembly, and a test surface sensing assembly which sense the radial position of the first journal surface, the second journal surface, and a test portion of the shaft, respectively, during rotation of the shaft. A transmitter of each surface sensing assembly transmits a runout signal which is received by a receiver of a computer. Within the computer, the runout signal from the test surface sensing assembly is adjusted with the runout signals from the first and second journal surface sensing assemblies to factor out deflection of the shaft caused by the standard rest and the shaft runout is computed and plotted using the normalized runout data.
