Total Number of Measurement Locations
Measurement locations correlate to the bearing locations
and their sequence follows the flow of energy beginning
from the free end of the motor to the end of the drivetrain.
Take measurements in this same order, beginning with
the free end of the motor and working downstream. See
Figure 4-1.
Fluke recommends that you make two measurements for
each component in the drivetrain (unless the bearings are
less than 36 in (1 m) apart). For optimum diagnostic
quality, make each measurement at the bearing location
when possible.
