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.
It is recommended to take two measurements from each
component in the drive train if the motor has more than
40 HP (29.8 kW) and is longer than 40 inches (101.6
centimeters). For motors with less than 40 HP (29.8 kW)
and 40 inches (101.6 centimeters) length, one
measurement is sufficient. For optimum diagnostic
quality, measure at each bearing location whenever
possible.
