It
is recommended that you start with the “Entry Level”
seminar if you cannot fully answer 80% of the following questions
with confidence:
·
What are, and, can I explain each of the 5 steps in most successful
PdM programs
·
Can I explain each of the 3 basic characteristics measured in
vibrations
·
Can I explain the effect that decreasing dynamic force has on
amplitude response
·
Can I explain the period of vibration
·
Can I explain the difference between a Natural Frequency and
a Resonance
·
Can I explain the difference between a Resonance and a Critical
Speed
·
What units are used to express amplitude and why use one over
the other
·
Do I understand what Phase is and when to use it
·
What is the most important Parameter Setup
·
Can I find and explain each of the basic menu selections in
my analyzer

What is a low frequency accelerometer? When do I use it? How
do I tell my instrument which accelerometer is connected?
·
Can I explain why and when to turn off Sensor Power
·
Do I know when to use Auto Range and why
·
Does a Shear Mode Accelerometer have advantages over Compression
Mode? If so, what are they?
·
