Information and tips on operating the instrument.
Intended use
- VIBXPERT II Balancer is intended for use as a portable balancing
device for the balancing of stationary machines equipped solely
with rotating components (rotors), e.g. turbine rotors, inductors,
circulating pumps, centrifugal compressors, fans, etc. This does
not include machines with oscillating components, e.g. all recip-
rocating machines.
- VIBXPERT II Balancer can be used without any restrictions for
the balancing of rigid rotors. Elastic (soft) rotors may only be
balanced with VIBXPERT at the resonant frequency (±25%) by
an experienced user. The measurement instrument and its acces-
sories may only be operated by authorized personnel.
- VIBXPERT II Balancer may only be used for the measurement of
machine signals in industrial environments while taking into con-
sideration the technical specifications.
- Transducers and cables may be used only for their respective in-
tended uses as defined in the corresponding sales leaflets.
PRÜFTECHNIK Condition Monitoring assumes no responsibility for
any damage arising from improper use.

Balancing safety notes
• The respective manufacturer’s instructions must be followed
when mounting balancing weights.
Make sure that attachment points for balancing weights to be
welded on are clean; clamp the ground electrode of the welding
device onto the rotor and not onto the machine.
For balancing weights that need to be screwed on, the maximum
permitted RPM of the motor must be observed.
• Themachinemustbedisconnectedinordertoworkontherotor
