Work Principle

When the pickup driven by a driver is making a linear uniform motion along the test surface,the contact stylus in perpendicular with the work surface is moving up and down on the work surface.Its motion is converted into electric signals, which are amplified, filtered and transformed into digital signals through A/D. The signals are then processed by the DSP into Ra and Rz values before displayed on the screen.
