Powerful, yet intuitive
VIBCODE®
Automatic measurement loca-tion identification byVIBCODE® ’fingerprint’ – thecoded ring!• No mix up of measurement
locations• Reproducible measure-
ments• Stable connection• Defined contact pressure• Defined measurement di-
rection
Simultaneous!Carries out two measurementsat the same time – with orwithout trigger/RPM as re-quired.• Dual channel measure-
ments for diagnosis andcorrection- orbit- cross phase- coast down- 2-plane balancing
• Independently selectabledual channel measurementtasks.
Portable!Lightweight design with carry-ing strap, ideal for machinerysurvey.
The best connections!5 robust color-coded connec-tors on the upper side of thedevice are stable, cannot beconfused and are dustproof.

VIBXPERT® at a glance
Single-handed operationInstinctive joystick operationwith ergonomically arrangedkeys.
VIBXPERT® with its comprehensivemeasurement and analysis func-tions and intuitive user operation isideal for routes.Together with the OMNITREND®
PC software, VIBXPERT® providesan important contribution to con-dition-based maintenance forpreventing unforeseen machinebreakdowns and expensive pro-duction losses.
VIBXPERT® lights upIf it‘s too dark, VIBXPERT® au-tomatically switches on thekeyboard illumination. Thelighted display allows work dayor night.
Expandable memoryReplaceable flash card pro-vides virtually unlimitedmemory (standard 2 GB).
Alarm displayto ISO standardsFour indicator LEDs onthe display indicate'Everything OK' (blue)‘Prewarning' (green)'Warning' (yellow)'Alarm' (red).
The attractive external design ofVIBXPERT® is also reflected in itsinternal structure: intuitive, graphi-cal user interface, straightforwarduser guidance and a constantlyavailable help function allow notonly skilled experts, but also aninexperienced novice to quicklyachieve reliable results.

Condition monitoringRegular recording of measure-ment values provides a clearpicture of the machine condi-tion trend.
The 2-channel VIBXPERT®
comes equipped with phasemeasurement, coast downmeasurement, orbit, cepstrum.
Optional Expert Diagnostics fea-tures can be added at any time:• Extended Time Waveform
collection• Transient data collection• Modal/ODS capability• Data export via Universal File
Export (UFF).
OMNITREND® manages machinedata, programs measurement tasksand routes, and archives the resultsin a database (MS Access, Oracle*,MS SQL*). Comprehensive func-tions are available for evaluationand documentation: alarm check,trend preview, multiview, bandanalysis, waterfall display, fre-quency markers and variouscursors.
Alarms & diagnosisIf there is an alarm, narrowband monitoring in the fre-quency spectrum shows thedamaged component. Fre-quency markers supportidentification of characteristicfrequencies typical for specifictypes of damage. Additionalfunctions for diagnosis can becalled up via a menu.
