3. പ്രവർത്തന തത്വം
The SRG-1 operates by moving its sensor along the measured surface at a uniform speed. The internal stylus displaces vertically according to the micro-uneven contour of the surface. This displacement is then converted into an electrical signal by the sensor. The electrical signal is amplified, filtered, and acquired by an A/D converter, transforming it into a digital signal. An embedded ARM processor processes this digital signal to calculate and display Ra, Rz, Rq, and Rt values.
