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.
