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)
To change the emissivity value:
1. Go to the Device Settings menu.
2. Push and to highlight Material Emissivity.
3. Push to open the menu.

• 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 23.

About Measurements
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.

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 34.
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.

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.

Trending
Trending, or repeated vibration measurements kept in a
spreadsheet over time, is the best method to track
machine health. The product CD supplies a custom
Microsoft Excel template that helps you to evaluate the
measurements. See Export Data on page 37 for more
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.
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).
36
Vibration Meter
Export Data
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).
Export Data
The export data feature lets you move data from the Meter
to a PC through the USB connection. The product CD
supplies a custom Microsoft Excel template that helps you
to evaluate the measurements. The template includes
fields for:
• Device ID (the Meter from which the data was
downloaded)
• Machine ID (the machine on which the test was
performed, machine ID may contain two levels)
• Machine Category (such as pump or compressor)
• High frequency/bearing measurement (Crest Factor+)
• Low frequency reading (overall vibration)
• Temperature
• Time and Date
