Graduation error is the maximum difference between the angle measured by a single readhead and the true rotation of the encoder as graduated. Application disturbances such as eccentricity are not included.

System error is graduation error plus SDE.

Effects such as eccentricity influence installed performance; for application advice please contact your local representative.
