Bi- The effect of probe misalignment and contact friction will result in radius changes with scanning direction if a suitable
directional calibration procedure is not used.
scans Mechanical hysteresis within a probe mechanism is best demonstrated by a bi-directional scan.
Therefore, Renishaw have decided to take the high integrity approach of quoting ring gauge metrology using bi-directional
scan data to demonstrate the performance of the Renishaw probe and calibration method.
