2 Work Principle
When the pickup it triggered, it is making a linear uniform
motion along the test surface, the contact stylus is
perpendicular to the work surface and is moving up and
back. Its motion is converted into electric signals which are
amplified, filtered and transformed into digital signals and
processed by the DSP into Ra and Rz values before
displayed on the screen.
