Working PrincipleThis instrument adopts needle scanning method to test the surface roughness of the work piece.
When measuring roughness of part surface, the probe is placed on the surface of the part and then tracing the surface at constant rate. The probe acquires the surface roughness by the sharp stylus in probe. The roughness causes displacement of probe which results in change of inductive value of induction coils thus generate analogue signal which is in proportion to surface roughness at 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 ARM chip and the measuring result can be read on OLED display. The results can be printed by Bluetooth printer.

sampling length especially when the arc is small;
③ Raise the slide adjustment rack of pillar slightly above the work piece surface, fall the probe till
contact with the work-piece. In the process, you should be careful especially when the probe is about to touch the work-piece;
④ Make the probe stylus point at the surface peak (or lowest point);
⑤ Adjust the body of the probe to the visual level state, observe whether the stylus position is
near the center;
⑥ Before measurement, move the work-piece to the right half of the measuring range, press start
Indication calibration,
Use the single-scale line for calibration
