Emissivity Selection

The correct emissivity value is important for you to make
the most accurate temperature measurements. Most
painted or oxidized surfaces have an emissivity of 0.93
(default value set in the Meter). This is correct for non­contact temperature measurements on most bearing
housings.

Inaccurate measurements can result from shiny or
polished metal surfaces. To compensate, put masking
tape or flat black paint on the measurement surface. Make
sure that the tape is the same temperature as the
measurement surface before you make a measurement.

For other applications the Meter has additional preset
emissivity values:

• Aluminum (e=0.30)

• Iron (e=0.70)

• Steel (e=0.80)

• Paint (e=0.93) – default value

• Wood (e=0.94)

• Concrete (e=0.95)

About Measurements

The Meter measures bearing health and the overall
vibration condition of a machine. Three types of
measurements are available: bearing vibration, overall
vibration, and temperature. Vibration measurement units
are user-selectable. More information about how to
change these units is on page 9.

For the best measurements, use these guidelines:

• Push  and position the Meter perpendicular to

the test surface.

• Push the sensor tip onto the test surface, on solid

metal, and as close to the bearing as possible until the
green LED turns on.

• Hold Meter in position with a consistent force until the

green LED turns off. The test results show on the
display.

In most applications the default RPM setting of >600 RPM
is correct. You must change this range for low frequency
applications where the shaft rotation is <600 RPM. A
severity scale does not show on the display when the
setting is <600 RPM. More information about how to
change the RPM setting is on page 22.

Crest Factor+ (High Frequency Measurement)

Crest Factor is the ratio of the peak value / RMS value of a
time domain vibration signal. Vibration analysts use this
ratio to find bearing faults. However, the Crest Factor
method has a key limitation. The Crest Factor increases
during initial bearing degradation when the peak value
increases. It then decreases as the bearing damage
worsens and the RMS value increases. A low Crest Factor
value could show a healthy bearing or a significantly
degraded bearing. The problem is to know the difference
between the two.

The Meter operates with a proprietary algorithm,
Crest Factor+ (CF+), to overcome this limitation. To make
interpretation easy for the user, the CF+ value shows a
severity range. The higher the CF+ value is, the more the
bearing damage. Table 5 shows the relationship of the
values of CF+ to vibration severity.

The CF+ value shows for each measurement in the
Bearing field on the Meter display. Push  and  to toggle
between the CF+ value and the high frequency vibration
level in units of acceleration.

Overall Vibration (Low Frequency) Measurement with Severity Scale

An overall vibration, or low frequency, measurement
includes a severity scale. The severity scale is an on­screen tool that interprets the vibration wear as good,
satisfactory, unsatisfactory, or unacceptable. More
information about the severity scale is on page 31.

For this measurement, you must set the Meter to
recognize the type of machine, or Machine Category, for
the test. A list of the most common categories is
programmed into the Meter. When the Meter is set to a
category, it can adjust for the usual vibration levels of
different machine types. This gives you the best accuracy
in the severity scale.

After these parameters are set, the Meter shows the
overall vibration and bearing measurements with a severity
scale for each measurement. The overall vibration severity
scale uses a statistical analysis of data from thousands of
industrial machines. Keep in mind when you use the
severity scales:

• The severity scales are only applicable to machines at

speeds from 600 RPM to 10,000 RPM.

Note

Severity scales do not show if the RPM range is
<600 RPM.

• Make measurements with the accelerometer as close

as possible to the bearing housing.

• The severity scales are not applicable if the machine is

installed on spring or pad isolators.

• Severity scales for motors match the machine that

they operate. For example, when you do a test on a
motor that operates a centrifugal pump, select the
applicable centrifugal pump Machine Category for all
test points on the motor and pump.

• Gearbox severity scales are applicable only for single-

stage, rolling element bearing gearboxes.

Vibration Meter

Interpret Results

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.

Table 6. Severity Scale

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

ISO 10816 Standards

As an alternative to the Overall Vibration Severity Scale
included in the Meter, you can use the ISO Standard
10816-1 to evaluate the severity of overall vibration levels.
Table 7 is a chart that contains the values from this
standard. You can compare the overall vibration value
measured with the Meter to this table to identify the
vibration severity.

information about the template and measurement plots.

The Excel template also can give an Overall Vibration
Severity that refers to one of three ISO Standards:

• 10816-1

• 10816-3

• 10816-7

A brief description of each standard and terms is as
follows:

ISO 10816-1

This standard contains general guidelines for machine
vibration measurements on non-rotating parts.

Key terms

Class I: Individual parts of engines and machines
integrally connected to the machine in normal
operation. Production electrical motors at a maximum
of 15 kW are examples of machines in this category.

Class II: Medium-sized machines (typically electrical
motors with 15 kW to 75 kW output) without special
foundations, rigidly mounted engines or machines (up
to 300 kW) on special foundations.

32

Vibration Meter

Interpret Results

Class III: Large prime-movers and other large
machines with rotating masses mounted on rigid and
heavy foundations that are relatively stiff in the
direction of the vibration measurements.

Class IV: Large prime-movers and other large
machines with rotating masses mounted on
foundations that are relatively soft in the direction of
vibration measurements (for example, turbo generator
sets and gas turbines with outputs greater than
10 MW).

ISO 10816-3

This standard is used to evaluate machine vibration by
measurements on non-rotating parts, for industrial
machines with nominal power above 15 kW and nominal
speeds between 120 RPM and 15,000 RPM when
measured in situ.

Key terms

Rigid: A machine foundation with the machine
supports rigidly attached to the machine skid and/or
the solid floor of the facility.

Flexible: A machine with flexible attachment between
the machine supports and foundation or facility floor.
The most common example of this is a machine in
which vibration isolators (flexible vibration damping
mechanisms) separate the machine and foundation.

Group 1: Large machines with rated power above
300 kW and not more than 50 MW (electrical
machines with shaft height: H ≥315 mm).

Group 2: Medium-sized machines with rated power
above 15 kW up to and including 300 kW, electrical
machines with shaft height 160 mm ≤ H <315 mm.

ISO 10816-7

This standard is used to evaluate machine vibration on
rotor dynamic pumps by measurements on nonrotating
parts.

Note

The standard includes guidance for
measurements on rotating shafts, but this portion
is not applicable to the Meter.

Key terms

Category I: Pumps that require a high level of
reliability, availability, or safety (for example, pumps for
toxic and hazardous liquids, critical applications, oil
and gas, special chemical, and nuclear or power plant
application).

Category II: Pumps for general or less critical
applications (for example, pumps for non-hazardous
liquids).
