6.3. Error compensation
Error compensation is required during DRO installation as there
are errors due to ball screw pitch error or deflection & tilting of
axes. The error can be also because of measuring system.
This error can either be linear or non-linear. These errors can be
determined either with the help of reference measuring system or
a slip gauge.

6.3.1.1. Linear Error Compensation (LEC)
Linear error compensation can be applied, if the results of the
comparison with a reference standard show a linear deviation over
the whole measuring length. In this case the error can be
compensated by the calculation of a single correction factor.
