Measurement Principle
When measuring surface roughness of workpiece, the pickup is placed
on the surface of the part and then tracing the surface at constant
rate. The pickup acquires the surface roughness by the sharp stylus
in pickup. The roughness causes displacement of pickup 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 processor and
the measuring result can be read on LCD, printed through PC.

Roughness Comparator (30 pcs/set)
This set contains standards of the six most important machining
methods in the prevalent "AA" values. These surface roughness is
used to compare and determine the degree of the surface finish by
comparision method and eye estimation or magnifying glass.The
surface rough contast blocks is made of 45 super carbor steel
except the GCr15 which is using to plat lapping the sample block.
All 30 speciments are calibrated in u''AA (Arithmetical Average)
and in the metric equivalents um Ra.
