Introduction
Introduction
VIBTOOL is a robust hand-held measurement instrument
with built-in sensors for vibration, RPM and temperature.
These sensors can be used to measure the following 5
parameters:
Vibration acceleration
Vibration velocity
Bearing condition (Shock Pulse Method)
Cavitation
Temperature
RPM
Two operating modes are available:
1. ‘Bluetooth’:
VIBTOOL obtains the measurement parameters from an
associated PDA computer via a wireless Bluetooth con-
nection. The measurement results are transferred to the
PDA computer and, from there, evaluated and saved
using special software.
2. ‘Preset measurements’
VIBTOOL contains measurement tasks with preset pa-
rameters. The measurement results can only be dis-
played. It is not possible to store the data on or to
transfer them to a PDA.
External vibration or temperature probes can be plugged in
to measure at locations that are difficult to reach.
VIBTOOL's primary function is as a 'multimeter' for general
on-the-spot measurements. Engineers can walk around the
machine hall with VIBTOOL and take immediate measure-
ments of machine conditions. Try it out...

Operation
While charging VIBTOOL, switch it off to keep the charging
time as short as possible.
VIBTOOL behavior during charging
1. VIBTOOL power is off – Power supply unit is plugged in:
If VIBTOOL is not fully discharged, the device switches
on and the messages ‘Char’ (= Charge) + ‘Strt’ (=Start)
appear consecutively on the display.
VIBTOOL then switches off while battery charging con-
tinues.
If the battery is fully discharged, the device switches on
and off repeatedly until it continues charging while it is
switched on (see also Point 2).
If VIBTOOL is left inactive, it switches off automatically
after 10 minutes.
2. VIBTOOL power is off – Power supply unit is removed:
VIBTOOL switches on. The message ‘Char’ - ‘Stop’
appears on the display for 7 seconds. Also, ‘Lo’ or the
battery charging level in percent appears before VIB-
TOOL switches back off.
3. If VIBTOOL is switched on while it is being charged:
VIBTOOL is ready for operation and the ‘Batt.’ symbol
lights up steadily to indicate charging.
4. If VIBTOOL is switched off while it is being charged:
The display switches off and charging continues.
5. VIBTOOL power is on – Charging stops (power supply
unit is removed or battery is full):
VIBTOOL remains ready for operation and the ‘Batt.’
symbol goes out.
6. VIBTOOL power is off – Charging is completed:
VIBTOOL switches back on and the messages ‘full’ +
‘charge’ appear consecutively on the display.
Press the M key to switch to operating mode, or switch
VIBTOOL back off: Unplug the charger from the mains
or press the UP/DOWN keys simultaneously.

Typical measurement procedure
Bluetooth operating mode
VIBTOOL receives all information for measurement via
Bluetooth from a PDA computer. This computer is used to
create measurement tasks with the corresponding soft-
ware.
Bluetooth mode is signified by ‘bt’ at the bottom of the
screen. In this mode the tool is ready to pair* with a host
device, or if it is already paired, to begin taking readings. A
Bluetooth pairing is not lost when the VIBTOOL is turned
off. A VIBTOOL can only be connected with one host device
at a time. When the VIBTOOL is communicating with a host
device vie Bluetooth, the ∆icon appears in the lower left
corner of its display.
Once VIBTOOL has been switched on, the ‘No data’ mes-
sage appears on the display. VIBTOOL is now ready to
receive the first measurement task:
After the measurement task has been received, the ‘rdy’
(ready) message appears. At the same time, the corre-
sponding measurement symbol flashes – e.g. for a vibration
measurement:
‘no data’ appears when
the device is switched on
Measurement task received
- ready to measure
Operation
* The host device must pair
with a Bluetooth peripheral
device before they can
communicate. Pairing consists
of exchanging information that
allows the two devices to
uniquely identify each other.

Note
VIBTOOL carries out several individual measurements
which are then averaged to produce a final result. VIB-
TOOL automatically sends the final result to the PDA.
To extend the measurement recording period, keep the
M key pressed. VIBTOOL starts the individual measure-
ment when the M key is released.
The measurement result is shown on the display until the
next measurement task is received.
If an external sensor is connected to VIBTOOL, this
sensor must also be used to carry out the measure-
ment! In this case, the integrated sensors are not used
for measurement.
