Operating Overview

You can use the instrument to perform the following tasks:
Balance machines using single and dual plane methods
•
Take live, free run measurements for onsite analysis of
•
vibration spectra and waveforms

Balancing

You can analyze and correct rotating mass imbalance problems
in-situ. A rigid rotor can be balanced in one or two planes.
Take an initial measurement of the imbalance.
•
Attach a trial weight to the balancing plane and take another
•
measurement. For dual plane balancing, do the same for the
second plane.
Attach correction weights to the balancing planes as
•
recommended by the instrument.
Take a measurement in each plane to confirm that the rotor
•
is balanced. Any residual imbalance can be removed via trim
balancing.
