Charting your results
Ultrasound will be produced differently for all types of systems. It may be strong
on one side of a bearing shaft, and weak on the other, depending upon the
unique wear patterns. Therefore it is very important to mark the test point, so that
future readings can be taken from the exact same position. Doing the same test
with the sensitivity set differently can completely change the results, therefore it
is extremely important to keep track of the instruments settings for future tests to
be valid.
A chart is provided in the back of this manual to help you keep track of your
results. This can help you easily see the changes or inconsistencies which
indicate problems. The chart also acts as a report card and helps you give a
much more accurate diagnosis of system health.
Keep this information in your files, or tagged on the equipment itself. When
returning to the same equipment, perhaps several months or even years later,
you have the information you need to make a decision as to the degree of wear
in a particular piece of equipment.
It is worth while to show this information to your customers. Letting them know
what is going on will help build your reputation, credibility, and make you more
profits in the process. Maintenance agreements are much easier to sell when
they include AccuTrak

testing. More scheduled repairs and less emergency
repairs keeps your business under control, as well as your clients temper.
Vibration
Vibration, misalignment, or moving machinery which is not properly balanced can
be deadly to a system. These things can cause leaks, and excessive wear
bringing the life of any system to an early demise.
All these problems have a common warning signal:
increased ultrasonic energy
.
This ultrasonic energy is generated from the friction associated with these
problems, and can be detected with the AccuTrak
®
. With experience, you will
know what readings are good, and which are bad for the most common types of
equipment you work on.
Example: If you are responsible for maintaining the A/C units in a large
residential area such as an apartment complex, where all residences use the
same cooling unit. After testing a sample of compressors, you soon will be able
to easily determine what readings are normal or abnormal for a particular model.
