Reflective mark
Cut and peel adhesive tape provided into approx. 12mm (0.5") squares and apply
one square to each rotation shaft.

b.
If the shaft is normally reflective, it must be covered with black tape or black paint
before attaching reflective tape.
c.
Shaft surface must be clean and smooth before applying reflective tape.
2-2
Very low RPM measurement
As it is easy to get high resolution and fast sampling time, If measuring the very
low RPM value, suggest user to attach more "REFLECTIVE MARKS" averagely.
Then divide the reading shown by the number of "REFLECTIVE MARKS"
averagely. Then divide the reading shown by the number of "REFLECTIVE
MERKS" to get the real RPM.
2-3
