When measuring roughness on specimen surface, the probe is placed on the surface of the specimen, and then tracing the surface at constant rate. The probe acquires the surface roughness by the sharp stylus inside. The roughness on surface causes displacement of stylus which results in change of inductive value in induction coils, thus generates analogue signal which is in proportion to the tested surface roughness at the output end of phase-sensitive rectifier. This signal enters data collection system after amplification and level conversion. After that, those collected data are processed with digital filtering and parameter calculation by DSP chip and the measuring result can be read on LCD, or printed out through printer or communicated through PC.
