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.

Safety
General safety notes
The following notes must be carefully read and completely under-
stood before the device is put into service.
• Duringmeasurementonmachineswithrotatingpartsexposed,
ensure that no brackets, cables etc. can become caught in rotat-
ing machine parts.
• Themeasurementdevice may onlybeoperated ifitisundam-
aged, dry and clean.

• Onlyoriginalsparepartsandaccessoriesmaybeused.
• Onlyproperlyfunctioning,regularly-maintainedelectricalequip-
ment may be used. Any defects such as broken plugs or loose
sockets must be corrected immediately. Damaged cables must be
replaced by an authorized service technician.
• Anyalterationsthataffectdevicedesignoroperatingsafetyare
not permitted.
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.
• Themachinemustbedisconnectedinordertoworkontherotor

dance with the applicable regulations.
• Beforetherstmeasurement(initialrun),itisimportanttoensure
that the preparatory activities have been carried out correctly and
completely. In addition to the assembly of measurement com-
ponents, particular attention must be paid to the correct input

result. This could have serious consequences for personnel and
machine!
• Nooneisallowedtoremainintheradialvicinityoftherotordur-
ing balancing runs. This area must be properly secured against
unauthorized entry. If the trial weight of the rotor on a running
machine detaches, there is a risk of fatal injury in this area!

on the rotor, weld any cracks on the impeller or replace the impel-
ler).

Power supply
VIBXPERT is supplied with energy by a Lithium-Ion rechargeable bat-
tery. With the power on the battery icon on the display indicates the
residual charge of the battery.
Follow the safety notes enclosed with the charger.
Connect the VIBXPERT charger either
to channel A or to channel B.
Description
Attention!
If the battery is almost empty, a message appears on the display
and the blue LED flashes. The battery can be charged either in the
device or in the external charging station (option, VIB 5.324) using
the VIBXPERT charger (VIB 5.320-INT).

Reports
VIBXPERT can generate the following report types:
Screenshot: Contains the content of the current screen.
Measurement report: Contains the measurement results and infor-
mation on the operator and measurement.
The reports can be printed directly to a USB-printer or to a PDF file.
The PDF file can be stored on a USB pendrive. Using the ‘VIBXPERT
utility’ tool the PDF file can be copied to a PC and printed from
there.
Details on configuring the measurement report, selecting the
PDF printer and transferring PDF files to a PC can be found in
the VIBXPERT II Balancer manual (art. no.: LIT 53.203.EN).
Loading reports onto USB pen drive
Reports in PDF format can be transferred to a USB pen drive and
then to a PC, where they can then be printed.
To do this, you need the following:
• VIBXPERT adapter for USB pen drive - VIB 5.330 MEM
• USB pen drive - VIB 5.330-USB
Connect the USB adapter to the communication channel (green
jack). In the file manager, the USB pen drive is shown as a separate
directory ‘USB’.
