Set Up Procedure:
1.
Connect the accelerometer to the input connector on the right side of the unit by
threading the socket gently until it locks in place.
2.
Press the
Power
Button to turn unit on.
3.
Place the accelerometer, with the magnetic base firmly attached to the machine. You
should allow a few seconds for the readings to stabilize before taking a reading. Machine
vibration may vary with time, in which case the maximum and minimum readings may
be recorded. The machine surface must be sufficiently flat to permit the magnetic base to
solidly attach to it. If the magnetic base is not attached properly, you will not be able to
obtain accurate readings at higher frequencies. If the measurement surface is not
magnetic or if the space is limited, the “Stinger” probes can be used in place of the
magnetic base. When using the Stinger probe hold the tip against the machine with just
enough force to prevent chattering. The stinger must be positioned perpendicular to the
desired measurement surface.
A steel disc or washer may be cemented to a non-magnetic surface to permit usage of the
magnetic base. For Maximum accuracy of Acceleration (g) measurements, the
accelerometer should be temporarily mounted on the machine surface with the supplied
(M5) threaded mounting stud.
Measurements made in more than one vibration mode can reveal something of the nature
of the vibration signal. A high acceleration reading combined with a low displacement
reading is indicative of a high frequency vibration. Conversely, a low acceleration
reading combined with a high displacement reading is indicative of a low frequency
vibration. Velocity is usually the preferred measurement when a single reading is to be
recorded. Consult the machines operation manual or the manufacturer if you are in doubt
of the measurements to be made.
The supplied vibration chart should be used as a guideline for determining machine
condition. The best indicator of machine condition is a carefully collected and recorded
history database. Changes in machine condition over time become readily apparent and
permit repairs to be made prior to machine failure.
