Vibration Meter

Interpret Results

The Meter is a screening tool to identify machinery

problems for more diagnostic tests. The Meter has a

vibration severity scale for Bearing and Overall Vibration

measurements. It can also trend vibration measurements

over time. If a measurement shows high vibration severity,

or if there is an adverse trend in vibration severity over

time, then the machine can have a problem. Fluke

recommends that you consult a vibration specialist for

more tests to find the root cause of these problems.

Severity Scale

Measurements with a machine ID, machine category, and

rotational speeds >600 RPM includes both severity scales.

A good measurement always finds some vibration. There

are four severity levels: good, satisfactory, unsatisfactory,

and unacceptable. A measurement in the good category is

an indication of a healthy machine.

Table 6 lists the different severity scales.

Scale Action

No repair action is recommended.

No immediate repair action is

required. Increase the frequency of

measurements and monitor the

condition of the machine.

Have a knowledgeable vibration

technician conduct more advanced

tests at the earliest opportunity.

Consider maintenance action at the

next planned downtime or

maintenance period.

Have a knowledgeable vibration

technician conduct more advanced

tests as soon as possible. Consider

immediate shutdown of the

machine to make repairs and

prevent failure.
