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...

Safety notes
The VIBTOOL housing may only be opened by authorized
technical personnel.
Operation and maintenance are to be performed only by
properly trained personnel.
Repairs to the VIBTOOL instrument may be carried out
only by a PRÜFTECHNIK-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 techni-
cian.
Any alterations that affect instrument design or operating
safety require explicit prior approval of PRÜFTECHNIK AG.
The relevant safety regulations must be observed during
measurements on machines.
Authorized use
- VIBTOOL may only be used to record machine vibration
signals, rotational speed and temperature values as well
as condition parameters of roller bearings in industrial
environments.
- For measurements with external transducers and for
data transmission via serial interface, only use the
connecting cable provided for this. Transducers and
cables may only be used for their respective intended
tasks as described in the corresponding product summa-
ries.
Any other use constitutes improper use and is prohibited.
PRÜFTECHNIK AG assumes no liability for damage result-
ing from improper use.
Moreover, the European installation instructions EN
60079-10:2003ff must be followed.
Attention!

Explosion hazardous areas
• VIBTOOL with intrinsic safety (VIB 2.700 EX) may only
be used with rechargeable batteries with the following
approval:
ZELM 05 ATEX 0243 U
• Rechargeable batteries must not be charged in explosive
environments! Only VIB 2.720 (EU), VIB 2.721 (USA) or
VIB 2.722 (UK) charging units may be used.
• The battery should not be removed under any circum-
stances! To replace a defective battery, VIBTOOL must
be sent back to the manufacturer.
• The accessories listed in the ‘Sensors & Accessories’
product catalog (VIB 9.663-1DG) are not allowed in
areas that contain inflammable dust!
• The VIBTOOL case (VIB 2.729) is not allowed in
explosion hazardous areas.
• Interface specification:
Analog output circuit: if the intrinsic safety protection is
type EEx ib IIC, it is only suitable for connection to
devices intended for this
UO= 11.6V
IO= 15mA
PO= 180mW
Ci= 70nF
CO= 1.5µF
Li= 300µH
LO= 60mH
Temperature sensor circuit: if the intrinsic safety protec-
tion is type EEx ib IIC, it is only suitable for connection
to devices intended for this
UO= 11.6V
IO= 15mA
PO= 180mW
CO= 1.5µF
LO= 60mH
Digital output circuit / charging socket: if the intrinsic
safety protection is type EEx ib IIC, it is only suitable for
connection to devices intended for this
UO= 8.4V / IO= 84mA
PO= 180mW / CO= 6.8µF
LO= 3mH
