4-2 Photo RPM measurement
1)Select ( default ) the function to " Photo RPM ", refer

when the target pass through the light beam.
Measuring consideration :
If the measured RPM values is very low ( for
example less than 50 RPM ), recommend to attach
more " Reflecting Marks " average to the object. It
will get the real RPM with high resolution, precisely
& fast sampling time when divided the reading
values by the no. of the " Marks ".
