NOTE:
Before to use the accelerometer screw the magnetic
stud to the sensor and remove the protection disk from
the base.
Place the sensor on rigid parts of the machine (such as
support bearings). All 3 orthogonal directions (X, Y and
Z) are recommended.
Put the reecting tape on the shaft; place the photocell
on the machine casing using the magnetic stud.
Point the photocell spot to the reective tape
previously positioned on the shaft.
