Adash 4900 – Vibrio III

Quick Start
The aim of this chapter is to introduce you to this instrument, and, without reading a complete User’s
Guide, enable you to measure first vibration values. This chapter does not intend to fully and in detail
describe operation of this instrument or measurement methodology. Special chapters in this Guide are
intended for this purpose.
Preparation of Measurement Point
We have to select a measurement point before the measurement itself. We want to choose it in such
way that transmission of vibrations would not be attenuated. Usually this means as close to the source
of vibrations as possible (for instance at a bearing housing). We always have to measure at solid, firm
part of a machine. We should not be measuring on covers and so on. The place should be clean,
without corrosion and paint. It should also be flat so a sensor would not “wobble”. The best is to use a
measurement base, which is glued on a machine. It has a perfect finish, plastic cover, and is made
from magnetic stainless steel. This will enable you to perform the measurements on the machine at
any time under the same conditions. This measurement repeatability means that you will be able to
compare the values well.
To attach the sensor use a magnetic sensor base (do not forget to remove a magnet cover from it,
which closes a magnetic field and protects the magnet from long-term weakening in storage).
Putting in Batteries
Batteries are accessible after opening a lid at a bottom part of the instrument. Open the lid by pressing
its lower edge (the edge with hinge), the lid upper part opens easily - see figure. Do not ever use force!
Proper polarity is shown on the picture.
Do not forget to switch the instrument off before opening the power battery lid!
Never handle the power batteries with the instrument switched on!
