4.3 CONTACT TACH. MEASURE RELATED
PARAMETERS OF CONTACT SURFACE

4.3.1 The definition for related parameters of
contact surface
The related parameters of contact surface,
include Surface speed, Mov in g di st an ce ,
Custom circumference movin g di st an ce .
The definitions are as follows,
A. Surface Speed
The speed of tested surface.
B. Moving Distance
The moving distance of tested surface.
Moving distance, defined as s, is the
product of C0 (the circumference of
surface speed wheel) and n (the nu mb er

8

of rotation).
The calculation formula is as follows,
s = C0 n
C. Custom circumference moving d is ta nc e
When using surface speed whe el w it h
custom circumference, moving dis ta nc e
equals to the product of C (the custom
circumference) and n (the numb er o f
rotation). Custom circumference can be
defined by user, for details, see

5. CUSTOM CIRCUMFERENCE
SETTING.
The calculation formula is as follows,
s = C n
