Precautionary information VIBROTEST 60
Page 10 of 168 C102 853.002 © VTEST60E July 2013 4.46ff
1 Precautionary information
Application
The VIBROTEST 60 is specifically conceived for the purpose of
overall vibration, spectrum, process-value and tracking analysis
measurements.
Use of the instrument for any purpose other than these is
therefore outside of the design purpose.
The VIBROTEST 60 is of the latest technological design and is
operationally secure.
Unrelated and unpredictable events may occur if the
VIBROTEST 60 is used by untrained persons for any indiscri-
minate purpose. Any person given the task of using the
VIBROTEST 60 should have first read and understood the
operating instructions and in particular the precautionary
information it contains.
Indiscriminate usage
in the operating instructions is emphasized by the following:
Note:
Non-observance of the precautionary information may result in
the possibility of damage (in particular component damage) to
the instrument.
Service work
Service work to the instrument may only be carried out by Brüel
& Kjær Vibro service personnel or Brüel & Kjær Vibro
authorised service personnel.
Note:
Please check the power in your region and compare it with the
power range capability of the battery charger unit of the
instrument before commissioning.
The battery set of the VIBROTEST 60 must not remain in the
instrument during transportation!
The connections of the battery set must not be short-circuited!

VIBROTEST 60 Precautionary information

Note:
•VIBROTEST 60 should only be operated with its covers on.
•Do not touch the charging contacts under the instrument.
This could result in faulty operation of the functions due to
electro-static discharge.
•The use of mobile telephones within a distance of 5 m could
lead to malfunction.

2 Introduction
2.1 Tasks the VIBROTEST 60 can perform
VIBROTEST 60 offers extensive measuring functions in a
modular concept as a
•Vibration analyser
•Field Balancing instrument
•Data-collector.
VIBROTEST 60 is the realisation of a measuring instrument
technically designed for evaluation of machine condition,
accurate diagnosis of damage and faults and achievement of
the most modern standard for „condition-based„ maintenance
strategy.
2.1.1 The concept
The modular concept of the VIBROTEST 60 permits individual
combinations of measurement functions and therefore opens
up a number of applications.
Functional modules of the instrument can be expanded at any
time and therefore future development of the measurement
functions can be easily supplemented.
2.1.2 Advantages of the VIBROTEST 60
•Unique FFT-analyser, Field Balancer, Data-collector in one
handy instrument
•Easily-understood operator dialogue, selectable in the
following languages:
−German,
−English,
−French,
−Italian,
−Dutch,
−Portuguese,
−Spanish,
−Czech,
−Hungarian,
−Polish

•Real 2-channel measurement plus speed
•Small, light-weight (900 g), single-hand operated instrument
•Latest quality in Data-collector technology with
−extreme speed of measurement and simultaneous
processing of up to 5 different measurement types
−multiple Routes and random Point processing in
measurement Routes
−random switching between analyser, field balancing,
and Data-collector modes
•High-tech signal processing with true Digital Signal
Processor (DSP)
•Guaranteed long product life-cycle through modular expan-
dable measurement functions for future developments
•High accuracy and dynamic resolution with 16-Bit ADC
•Excellent FFT resolution with up to 12,800 lines
•Commercially-available accelerometers, velocity and displa-
cement sensors can be used
•Brilliant, high-contrast graphic display with back-light
•Extreme storage capacity and high measurement data
security through use of PC-cards
