UNRESTRICTED DOCUMENT
2 Overview
The VIBROSTORE 100 (VST-100) is a simple to use rugged vibration monitoring and portable
analysis instrument with on-board display of vibration levels. VST-100 automatically performs
vibration analysis functions based on machine running speed. This functionality can help diagnose
faults such as unbalance, misalignment and looseness.
The system is designed to take vibration measurements from assets (e.g. pumps, motors, fans and
bearings) a simple route-based data collection mode. The unit displays vibration frequency plots and
allows vibration severity and bearing condition to be monitored. VST-100 will collect and display all
measurements in in as little as 3 seconds with one push of a button.
Combined with the powerful ReO software, the collected measurement data can be exported and
used to perform even more advanced analytics and computing tasks. ReO is able to display valuable
plots and graphs, to effectively detect and analyse vibration related problems of rotating machinery.
VST-100 supports an optional strobe attachment for determining machine speed it allows to connect
to Bluetooth headphones for listening to bearing noise.
2.1 Control buttons
The VST-100 features an OLED display and 7 control buttons. Please refer to section “Operation” for
a detailed description. When off, turning the VST-100 ON is achieved simply by pressing the center
button. The unit will automatically turn OFF if not used for a 1 to 60 minutes selectable auto turn off
time.
When the main menu is displayed the device can be turned off by pressing the button for 3
seconds.
2.2 Protective boot
The VST-100 is guarded by a removable protective rubber sleeve, which can be removed, by peeling

3.3 Fitting the sensor
VST-100 is supplied with a cable connected sensor (accelerometer) that connects to the BNC
connector on VST-100. The nominal sensitivity of the sensor is 100 mV/g.
VST-100 can also accept any standard IEPE (CCS) accelerometer and the sensor sensitivity setting
can be adjusted to accommodate other sensitivities (see section 3.5.2.3 in this manual). The default
setting is 100 mV/g.

3.4 Taking a reading
To take a reading, press the center button to
turn the unit ON.
Place the sensor on a rigid part of the machine as
close as possible to the desired measurement
point (e.g. bearing block) using the magnet mount.
Pressing the circle button again takes the
reading.
N.B. for best results the sensor should be
placed gently onto the measurement point by
“rolling” the magnet onto the machine.
This is to avoid any sudden shocks that would
be seen as large acceleration peaks by the
sensor and could take some time (several
seconds) to die away.
Taking a reading causes the overall vibration
numbers screen to be displayed as shown in the
example screen left.
This screen gives an overall view of the machine’s
vibration condition as explained in the following
section.

3.4.1 Vibration readings
WARNING!
Through electro-magnetic interferences (acc. to EN 61000-4-3) influences on the
measured values may arise.
Once a vibration reading has been taken, the display will show three values, as shown in the example
screen (see chapter 3.4 Taking a reading). The values are color coded to show their alarm status as
explained in the following sections. VST-100 can show the results as peak, peak to peak and root
mean square (rms) values.
The three values shown in the readings screen are:
•ISO value (velocity in mm/second or inch/s)
•Bearing Noise in BDU (Bearing Damage Units)
•Total g (acceleration)
These readings are explained in more detail below with some examples.

Page 16 of 32 ©Brüel & Kjær Vibro ●C107851.002 / V01
Technical alterations reserved!
EN
ISO value (mm/s)
The ISO value (in mm/s or inch/s) is the large number displayed at the top of the screen. This is the
RMS measurement of the calculated peak measurement of the vibration velocity in the frequency
band 10Hz (600 RPM) to 1kHz (60,000 RPM) or 2Hz (120 RPM) to 1kHz (60,000 RPM) as specified
by the ISO standard
1
. The correct frequency band is automatically selected by VST-100 based on
running speed.
The ISO value background is colour coded according to the ISO 10816-1 vibration velocity level chart
(see below). The colour coded background indicates the condition of the machine according to the
size and type of machine selected with the Setup Wizard (see section 3.5.1).

UNRESTRICTED DOCUMENT
Bearing Condition (BDU)
Below the displayed ISO value and to the left is the value of bearing noise(high frequency vibration) in
Bearing Damage Units (BDU), where 100 BDU corresponds to 1 g RMS vibration measured in the
frequency band between 1kHz and 10kHz. This is an indicator of the wear state of a bearing; higher
number = higher bearing wear.
It is commonly held that 1g of high frequency vibration (100 BDU) corresponds to a relatively high
level of bearing noise and so can be considered indicative of a damaged bearing. In other words, it
may be helpful to think of the Bearing Noise figure as being very roughly equivalent to “percentage”
of bearing wear. To quickly and easy identify the wear state of the bearings the background of this tile
is colour coded like the ISO value as well. By default, the bearing noise is displayed on a Red
background if it is above 100 BDU, a Yellow background between 50 and 100 BDU and a Green
background below 50 BDU. However, the BDU alarm levels can be changed using the Manual Setup
menu (see section 3.5.2.1).
Broadband acceleration (g)
This is the acceleration vibration value in g (RMS) of a bandpass filtered signal. The filter spans from
10Hz to 10kHz. This reading is shown in units of g (Earth’s gravitational constant, where 1 g = 9.81
m/s2).
Displacement (µm or mils)
Pressing either the left or right arrow button when the reading screen is displayed will cause
the VST-100 to display calculated peak or peak-to-peak displacement values (in µm or mils) on a blue
background. There is no alarm level coding. The frequency band is chosen analogue to the ISO value
measurement. Pressing either left or right arrow button again will revert to display of the ISO
value (mm/s or inch/s).
3.4.2 Vibration Analysis (Vibration bands)
Pressing the down arrow button brings up a display. It shows the readings of vibration velocity
(mm/s or inch/s), or displacement (mm or mils) if selected, broken down into each of 3 bands.
The display shows the vibration level in frequency ranges that are all based on multiples (1X, 2X and
3X) of the specified Run Speed of the machine as displayed beneath the 3 bar graphs.

Technical alterations reserved!
EN
N.B. in order to perform a vibration
analysis it is important that the running
speed of the machine is entered correctly.
This can be done with the “Setup Wizard”
as described in Section 3.5.1 of this user
guide, or by using the strobe attachment
(see Section 6.1)
Typical but not exclusive for the appearance of following multiples of running speed
2
are:
1X = Unbalance:
The level of vibration in the frequency band based on the running speed is usually indicative of how
well balanced the machine is. A large vibration at the running speed usually indicates that the
machine is out of balance. However even a very well-balanced machine will typically show some
vibration at the running speed, but this value should ideally be quite low (e.g. typically less than about
2 mm/sec for a medium sized machine).
2X = Misalignment:
A high level of vibration in the frequency band centred at twice the running speed is a possible
indication of misalignment. Shaft misalignment can result in a double peak in the waveform. This will
typically give rise to a vibration signal at double the running speed of the machine.
3X = Looseness:
High vibration in the frequency band centred at 3 times running speed is a possible indication of high
mechanical looseness (e.g. loose mounting bolts, weak foundations etc.).
2
Multiples of running speed are sometimes referred to as “orders”.

3.4.3 Frequency spectrum
Pressing the down arrow button once more brings up
a display, where the vibration levels are shown as a
frequency spectrum plot in the range from 0 to 1 kHz.
The heights of the peaks indicate the RMS vibration level
(in mm/s or inch/s) at each frequency point in the
spectrum.
The values to the right of the screen show the frequency
(in Hz or RPM) and the RMS vibration level (in mm/s or
inch/s) at the position of the cursor (red dotted line). The
cursor position can be moved by use of the left and
right arrow buttons.
Pressing the down arrow button increases the resolution of the frequency axis from 100 Lines
(i.e. 10 Hz or 600 RPM resolution) to 800 Lines (i.e. 1.25 Hz or 75 RPM resolution). Increasing the
resolution effectively zooms into the frequency spectrum. To display the full spectrum at the higher
resolution the display must be scrolled using the left and right arrow buttons.
3.4.4 Live Update Mode
It is possible to have the VST-100 continuously display readings that are taken at intervals of approx.
1 second.
Live Update is selected from the Configuration menu, which is entered by holding down the center
button for 2 seconds.
It is possible to use live update with the basic readings screen, the VA bands screen or 100 line
frequency spectrum. Pressing the center button at any time during live update will take a single
measurement and stop live update mode.

3.5 Configuration menus
The configuration menu is entered by pressing and
holding down the center button for 2 seconds.
Moving up and down the menu is achieved by pressing
the up and down buttons which causes the menu
item to be highlighted. Pressing the circle button will
select the highlighted menu item. Left and right
arrow buttons can be used to move backward and
forward through the menus.
All changed settings will be saved immediately and do
not require to be saved additionally.
3.5.1 Setup Wizard
Selecting the Setup Wizard opens a dialogue that allows
the machine running speed to be entered and the ISO
alarm levels to be set automatically according to the size
and type of machine to be monitored.
The first Setup Wizard screen to be displayed shows the
currently selected running speed in the pre-selected
units (Hz or RPM).
Changing the running speed is achieved by pressing the
up arrow button (to increase run speed) or down
arrow button (to decrease run speed). Pressing and
holding either of the buttons will quickly change the
displayed value.
