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.
