When measuring the roughness of a surface, the sensor is placed on the surface and then uniformly slides along the surface by driving the mechanism inside the tester. The sensor gets the surface roughness  by the sharp built-in probe. This roughness causes displacement of the probe which results in change of inductive amount of induction coils so as to generate analogue signal, which is in proportion to the surface roughness at output end of phase-sensitive rectifier. The exclusive DSP processes and calculates and then outputs the measurement results on LCD.

Attributions:

- RS-232 output (optional data cable and software)

- Manual/automatic shutdown

Roughness parameters:

Ra – average roughness
The average distance measured between the points of the surface and its midline along the cutoff length.

Rz – maximal roughness
Rz is the mean of the five highest and lowest value of the roughness function along the lenght of measurement.
