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 printer and communicated with PC.
