Foreword
Congratulations! And thank you for selecting the VIBXPERT II
FFT data collector and signal analyzer*. This newly developed
measurement device is not just the ideal companion for your routine
measurement round, but also a reliable on-site aid for recording and
analyzing complex machine signals.
VIBXPERT records all types of machine vibrations, bearing
conditions as well as process and visual inspection data, and
transfers this information to the OMNITREND maintenance software
for evaluation, archiving and documentation.
The combination of its extensive range of features and easy
operation makes VIBXPERT the effective choice for a wide range of
applications:
• High measurement accuracy and high-speed data collection
• Operating modes:
'Route' for routine data collection for condition-based
maintenance,
'Multimode' for individual measurements for machine diagnosis
'Balancing' in one or two planes (optional).
'Machine templates' for recurrent measurement tasks within the
scope of acceptance or service measurements
• Almost every type of sensor can be connected
• One or two measurement channels (analog);
Upgrade to 2-channel device at any time via password.
Hardware
• Two synchronous measurement channels for diagnosis of
complex measurements (e.g. shaft vibration).
• Sufficient storage capacity (2 GB CompactFlash).
• Dustproof and splashproof (IP65) - ideal for use in demanding
industrial environments
• Connector technology compatible to VIBSCANNER (same cable)
• Connector for NiCrNi thermocouples
• Connector for headphones
Data collection and data analysis
• Overall values
- Vibration acceleration, velocity, displacement
- Current & voltage (process parameters)
- Shock pulse (bearing condition)
- Temperature
- RPM
• Signals
- Frequency-based and order-based data collection
- Amplitude, envelope, order spectra
- Cepstrum
- Time waveform
- Phase measurement (synchronous, cross channel)
- Dynamic shaft movement (Orbit and shaft displacement)
Foreword
* Also referred to as 'VIBXPERT' and
'device' in these operating instructions.

- Transducers and cables may be used only for their respective
intended uses as defined in the corresponding sales leaflets.
Any other use shall not be considered an intended use and is
impermissible. Incorrect or impermissible use and failure to observe
the instructions in this manual result in a loss of warranty from
PRÜFTECHNIK.

General safety
The following notes must be carefully read and completely
understood before the device is put into service.
Risk of injury when measuring on a running machine!
Observe the safety regulations. Install the measurement equip-
ment properly. During measurement on machines with rotating
parts exposed, ensure that no brackets, cables etc. can become
caught in rotating machine parts.
The measurement device may only be operated if it is undam-
aged, dry and clean.
Operation and maintenance are to be performed only by prop-
erly trained personnel.
Repairs to the device may be carried out only by a PRÜFTECH-
NIK-authorized service technician.
Only original spare parts and accessories may be used.
Only properly functioning, regularly-maintained electrical
equipment 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.
Any alterations that affect device design or operating safety are
not permitted.
Environmental influences
Portable radio-based devices can interfere with proper func-
tioning of the device when operated nearby. In case of doubt,
check the connecting cable between the device and its trans-
ducer.
Avoid exposing the device, its transducers and cables to envi-
ronmental conditions that exceed the tolerances listed in the
‘Technical Data’ section at the rear of this manual.
Keep the protective caps on the connector sockets when they
are not in use to keep them clean.
How to deal with rechargeable batteries
• Charge the battery only with the VIBXPERT charger.
• Maximum charge temperature: 40°C.
• Follow the safety instructions enclosed with the charger.
• Do not use damaged batteries!
• Do not use force to open the battery or throw it in the fire!
• Do not short-circuit connection contacts!
• Dispose of used batteries properly in accordance with regula-
tions.
• Do not send devices with defective batteries by air freight.
• During extended periods of non-use and during storage, con-
nect VIBXPERT regularly to the mains supply. This prevents the
battery from becoming completely discharged, and the date
and time settings are retained.

Notes on operation
To keep operation as simple and intuitive as possible, the graphical
user interface guides the user step-by-step and is based on the
'Microsoft Windows' operating concept.
Switch on / off
To switch on the device, hold the On/Off key down for two seconds.
VIBXPERT is ready for operation when the start screen appears. To
switch off, press the On/Off key again for 2 seconds and confirm the
resulting query to switch off with 'YES'.

Interfaces
The connections for the sensor and data cables are located on the
front of the measurement device. The cable connectors and sockets
are colored for easy identification.
To unplug the connector, push the connector sleeve backwards to
release the lock. Only then should you remove the connector from
the device. Never pull directly on the cable!
Analog
The blue channels marked with 'A' and 'B' are used as the:
- Input for analog signals
- Charging socket for the battery (A or B)
The sensor cable is connected to the channel (A or B) set in the
measurement task.
The analog measurement channels are not electrically insulated.
For 2-channel measurement on two machines, check the potential
equalization (VDE 0100) or use electrically insulated sensors.

Digital
The yellow channel is used as the:
- Input for digital signals from a trigger or a RPM sensor
- Serial interface for data transmission (RS 232)
- Output for the analog signal (connection for headphone/
oscilloscope)
- Output for stroboscope control (TTL signal)
The permissible range for trigger signals is:
-26V ... 0V (negative) or -5V ... +26V (positive).
Switching threshold positive: max. 2.5V rising
min. 0.6V falling
Switching threshold negative: min. -8V rising
max. -10V falling
The input signal must not exceed the switching threshold of the
positive and negative range as otherwise incorrect measurements
can occur.
Temperature
This interface is used for the connection of a thermo couple type K.
Communication
The green channel is used as the:
- Communication interface to the PC. The connection is established
via a network (Ethernet) or directly via a USB cable.
- USB printer port.
- Connection interface for an USB flash drive.
The network is configured in the 'Device Setup' (see 'Ethernet' on
page 2-34).
