Foreword

Structural analysis:

- Coast down / Run up analysis (natural frequencies, machine)

- Impact test (natural frequencies, machine components)

• Advanced measurements

- 1+1 dual measurement (simultaneous 2-channel measurement)

- Multitask (measure multiple measurement tasks in a sequence)

- On-site balancing in one or two planes

- TrendingSpectrum (a measurement provides a time signal, a

spectrum and several characteristic overall values, in route and

template mode).

- Recording

- Multiplexer measurements: Data collection via VIBRONET field

multiplexer

Ergonomics

• Large, backlit color display* ensures clear data presentation and

optimum readability

• Easy-to-use keypad

• Three alarm LEDs (red-yellow-green) indicate if thresholds have

been exceeded (based on ISO standards). A blue LED lights up if

everything is OK.

• Daylight sensor controls keyboard illumination

• Graphical user interface

• Color-coded connectors

• Online, context-sensitive HELP

Power supply

• Lithium-Ion battery of latest generation for more than 8 hours of

operation

• Smart battery charging in VIBXPERT

• Automatic power management (display, device)

Communication

• Fully networkable

• PC connection via USB, Ethernet, RS232.

Documentation

• Printing out of reports, directly on paper or as a PDF file.

VIBXPERT* from PRÜFTECHNIK once again demonstrates

the company's skills and innovative strength in the field of

maintenance, and is a consistent advancement in the series

of successful portable device systems such as VIBSCANNER,

VIBROCORD, VIBROTIP, VIBCODE.
Also, we would like to make you aware of the application-oriented

seminars offered by PRÜFTECHNIK that feature a significant practical

segment. They are very well received by course participants and

you will find them to be a good investment.
