The Fluke 810 Vibration Tester with diagnostic technology
(the Tester) helps you quickly identify and prioritize
mechanical problems. With the Tester, you can make
decisions about mechanical maintenance and use it as a
supplement to your own judgment based on machine
knowledge. The expertise of a trained vibration analyst is
in your hands.
The Tester uses a simple step-by-step process to report
on machine faults the first time measurements are taken
without prior measurement history. The diagnostic
technology analyzes your machinery and provides textbased diagnoses, severity levels and possible repair
recommendations. Faults are identified by comparing
vibration data gathered by the Tester to an extensive set
of rules gathered over years of field experience.
Primarily used for troubleshooting problem equipment, the
Tester can also be used to survey equipment before or
after planned maintenance. The combination of
diagnoses, severity and possible repair recommendations
help you make more informed maintenance decisions and
address critical problems first.
Training is important to the success of vibration testing,
even for experienced vibration experts. Fluke
recommends you take the self-paced training program on
the Fluke website, www.fluke.com. The site also has
additional training programs, guides, and videos.

the machine under test. To create a new Machine Setup
name:
1. Push New Machine (F1) on the startup screen. Or
push . The tester displays the options:
• Set up new machine
• Copy Machine Setup
2. Select Set up new machine. An alphanumeric
keyboard appears.
For the best machine analysis and diagnosis, the Tester
has to understand the layout and components of the
machine. The Machine Setup wizard guides you through
several questions about the profile of the machine. These
machine setup values must be correct for valid diagnostic
results.
Note
All questions in the Machine Setup Wizard are
required to generate a diagnosis unless
otherwise labeled “optional.” Including optional
information will improve the results of the final
machine diagnosis.
Once you create a Machine Name, the Tester starts the
Machine Setup wizard and you enter the parameters of
the machine under test. The Machine Setup wizard
displays the options sequentially based on the input you
give and organizes the options into these categories:
• Motor Input (Driver)
• Coupling and Transmission
• Driven Components
Note

The Machine Setup Wizard uses combo boxes. A combo
box is a combination of a drop-down list or list box. You
can choose from the list of existing options. To make a
selection:
1. Push Enter to activate the combo box.
2. Rotate the Dial to highlight different options in the
combo box.
3. Push Enter to confirm the selection. Depending on
the component you select, the options appear for the
details of the component.
Entering an accurate running speed (RPM) is critical to
receiving a proper diagnosis. An accurate running speed
helps the diagnostic engine in the Tester discern different
fault conditions. The motor nameplate or manual also lists
the running speed.
If an ac motor uses a variable frequency drive (VFD), it
operates under a varying load that influences the
vibration signal. It is important to obtain the correct RPM
using a tachometer. Or, refer to the frequency on the
motor controller label. For consistent diagnoses over
time, it may be necessary to reduce or increase the load
on the motor to match the load from previous
measurements.
Measuring VFDs requires entering RPM at the time of
measurement (instead of relying on RPM values in the
Machine Setup) due to variable loads. To obtain an
accurate RPM value, use the Tachometer provided with
the Tester or obtain the frequency value from the drive
controller itself. To convert the frequency value to RPM,
calculate:
Hz * 60 = RPM
Horsepower (HP) or kilowatt (kW) input is required for the
diagnostic system to identify the number of measurement
locations.
Table 4-2 is a list of the options for the motor input.
When an RPM value has to be entered, the RPM entry
screen opens.
Use the Tachometer to measure the RPM. See
Tachometer Setup to set up the Tachometer and
measure the RPM. After you set the RPM value, the
Tester goes back to the Machine Setup wizard.

Sensor orientation is critical to ensure repeatable data
and consistent diagnoses over time. Once you have
mounted the Sensor onto the machine to be tested and
created a Machine Setup, the Tester is ready to measure.
W Caution
To prevent damage to the Tester, do not take
a measurement while connected to ac power
source.
Select Measurement Locations
The optimum measurement location is as close to the
machine bearings as possible. A solid metal surface
between the bearing and Sensor is ideal. The solid metal
casting effectively transmits the vibration signals emitted
by bearings. Do not put the Sensor on bearing caps, fan
housings, sheet metal shrouds, non-metallic materials,
and other metal-to-metal joints as they can significantly
distort the vibration signals.
Tips for measurement location:
•Do not mistake seal locations for a bearing
measurement location on pumps.
•Attach the Sensor to a clean, flat, bare metal surface
if possible. Thick layers of paint, grease, oil, or other
matter reduce both the holding force of the magnet
and the high frequency response of the Sensor.
•Avoid mounting the Sensor on thin surface areas,
such as fan shrouds and cooling fins.
•The position of the cable connection on the Sensor
should be parallel or perpendicular to the drive shaft
whenever possible.
•For close-coupled machines where the motor is
directly bolted to the driven component, take all
measurements from the motor. If motor is <40 hp
(30 kW), take the measurement from the motor’s
driven end. If the motor is >40 hp (30 kW), take the
measurement from both the motor’s driven end and
free end.
WWarning
•For consistent diagnoses over time, it is important to
measure with the same parameters. You must place
the triaxial Sensor at the exact same location on a
machine and with the same orientation.
•Do not take bearing measurements from a
foundation or fabricated base.
To prevent personal injury, do not allow
Sensor location and mounting to supersede
safety. Always consider the best
combination of locations and mounting
techniques that personal safety will allow.

Note

Number the bearings with the flow of energy.
Consistent Sensor orientation is critical to ensure
repeatable data and consistent diagnoses over time. The
Tester uses a triaxial Sensor that combines three
transducers into a single housing. These three
transducers simultaneously measure the vibration data
from three axes or directions:
• Axial (A)
• Radial (R)
• Tangential (T)
The axes are oriented to the drivetrain shaft and vary
depending on the horizontal or vertical orientation of the
drivetrain. See Figure 4-2.
Note
If you define the Sensor orientation incorrectly in
the user interface, the diagnostic engine is
unable to associate the vibration signals with the
correct axes. The result is a false diagnosis from
the Tester.
A
A = Axial
R = Radial
T = Tangential
A
Figure 4-2. Axes Orientation
The Tester uses the machine driveshaft as the common
reference point. You must set the orientation of the
Sensor cable as either parallel or perpendicular to the
driveshaft.
The Tester’s diagnoses are largely dependent upon the
quality of vibration signal it receives from the machinery
under test. The method used to mount a Sensor to the
machine directly affects the quality, accuracy, and range
of the signal, see Figure 4-3.
Stud Mount
In general, permanent mounts, such as stud or adhesive
mount, yield the best results. These are best for
machines that:
• run at high speeds and frequencies
• have a driving unit that runs at greater than
6000 RPM (for example, vacuum pumps)
•include a speed changer (gearbox) that results in an
output shaft speed of greater than 5x the input shaft
speed
•include an integrated speed changer (for example,
centrifugal compressors)
Permanent mountings promote more consistent data if
tracking machine condition over time. The advantages
and disadvantages of permanent mounts are as follows.
Stud mounting is typical for permanently mounted
applications. A hole is tapped into a flat section of the
machinery housing and the Sensor’s stud is screwed into
the tapped hole.
Advantages: Highest frequency response, very
repeatable data over time. Best diagnostic quality.
Disadvantages: Less practical for “walkaround”
troubleshooting due to time needed to screw/unscrew the
Sensor from machinery, often difficult to tap a hole in the
desired measurement location.
Adhesive Mounted Pads
Typically used for permanently mounted applications. A
thin layer of adhesive is applied to the bottom of the
mounting pad and placed on a flat section of the
machinery housing. The Sensor’s stud is screwed into the
hole in the mounting pad.
Advantages: High frequency response approaching that
of a stud mount without having to tap a hole, very
repeatable data over time. Next to a stud mount, best
diagnostic quality.
Disadvantages: Less practical for “walkaround”
troubleshooting due to time needed to screw/unscrew the
Sensor from mounting pad.
The advantages and disadvantages of a temporary mount
are as follows.
Magnetic Mounting
The magnetic mount uses either a 2-pole magnet (for
rounded surfaces) or flat magnet attached to the Sensor.
If you make the measurements at the exact same
location, each time, repeatable data can be collected over
time. Magnet mounts are generally more convenient and
allow faster measurement, but some accuracy is lost.
Advantages: Fastest, most convenient method for
“walkaround” troubleshooting.
Disadvantages: Diagnostic quality is less than that of
stud or adhesive mounts.
W Caution
When using a magnetically mounted Sensor,
be careful when attaching it to the test
surface. The magnet is very strong and could
pull the Sensor assembly from your hand
and impact the test surface. An excessive
impact can damage the Sensor. Hold the
Sensor firmly and carefully roll the Sensor
onto the test surface to minimize the
potential for impact.
Best practice is to take vibration measurements when the
machine is running in a steady state and at normal
operating temperature. Fluke recommends that you make
two measurements for each component in the drivetrain
(unless the bearings are less than 36 in (1 m) apart). For
optimum diagnostic quality, make each measurement at
the bearing location when possible.
Multiple measurements will improve the diagnostic
quality. You need to test all the components, but not
necessarily all the possible Sensor locations on each
component. Vibration transmits easily through a machine
and it will be picked up from each location.

To measure machine vibration with the Tester:
1. Push . The Measure screen shows the saved
Machine Setups ready for measurement.
2. Rotate the Dial to highlight a Machine Setup and
push the Dial or Enter (F3) to select the saved setup.
The Tester automatically detects and configures the
settings for the Sensor unless the drivetrain includes
a variable frequency drive (VFD) or dc motor. If there
is a VFD or dc motor, you must verify the RPM in the
RPM Entry screen which appears next.
3. To enter the RPM, choose a method:
• Retake the RPM measurement.
• Manually enter the RPM.
Note
The RPM entry is important. Fluke does not
recommend that you skip the RPM Entry screen.

The Tester configures the settings and detects the
Sensor.
Note
Because the current running speed is so critical
for correct diagnosis, it is a best practice to use
a Tachometer on VFD motor controllers. Or,
refer to the frequency on the motor controller
label before you take a measurement.
If a single axis Sensor is detected, the Tester asks
for the sensitivity of the Sensor.
4. To input the sensitivity value of the Sensor, push
Keyboard (F4) and enter the value.

Note
The first time you take a measurement, draw or
paint a line on the machine to indicate the
Sensor measurement location. Use an arrow to
indicate the Sensor orientation. If you take
measurements at exact same locations and
with exact same Sensor orientations, you can
push Use last orientations/locations. This will
bypass the location and orientation screens and
take you directly to the data collection screen.
6. Select New orientations / locations. The Sensor
Placement screen appears.
7. Rotate the Dial to select the location for the first
Sensor placement. Locations are shown above the
drivetrain image. The time available for taking
measurements is shown in the top right side of the
display.
Note
The vibration from a drivetrain may change
depending on the load and ambient temperature
of the motor. You must finish a measurement
within 30 minutes. If not, the “Measurement

reference. Orient the Sensor to the driveshaft using
the Sensor cable where it exits from the Sensor,
telling the Tester whether the cable is parallel or
perpendicular to the shaft.

How to Diagnose
Once the Machine Setup is complete and measurement
information is collected, the diagnostic engine analyzes
the data with a set of powerful algorithms. It also identifies
abnormal conditions and pending mechanical failures for
the machine.
Fault Types
The Tester can identify four of the most common
mechanical problems:
• Bearing Failures
• Misalignment
• Unbalance
• Looseness
The diagnostic engine can identify other mechanical
faults (nonstandard faults) in addition to these four basic
faults. However, it cannot provide any details on the type
of the fault, only its severity.
Displays the prioritized repair
recommendations related to a particular
diagnosis.
Displays the previous diagnosis with same
machine.
Displays fault details and cited peaks for
selected fault.
Overall Vibration
The Overall Vibration measurement shows in the upper
right of the Diagnosis screen.
Severity Scale
The scale is an indication of severity for any particular
fault machine condition.
SlightModerateSeriousExtreme
gbk13.eps
Note
The severity scale should not be associated with
time to failure.
The severity scale is based on the intensity of the
machine fault at the time of measurement. It is not an
indicator of time to machine failure. As conditions change,
the severity may change, even appear to improve (for
example, immediately after lubrication). However, over
time, conditions will worsen with normal machine wear
and tear.
Note
Time to failure will vary depending on the
equipment type, age, machine load,
environmental conditions, and other variables.
Follow these recommended actions for each severity
level to avoid failure. In general, the scale may be
interpreted as:
•SlightNo repair action is recommended.
Monitor the machine and retest after
regular machine planned maintenance
to verify maintenance was performed
correctly.
•Moderate(Months, even up to a year) – Repair
action may be needed in the future. A
machine failure is possible, so plan
accordingly. Increase the frequency of
vibration testing on this equipment and
review spare parts availability.
•Serious(Weeks) – Repair action may be
needed before the next planned
downtime. There may be other physical
evidence of the fault in terms of noise
or higher bearing temperatures. Retest
the machine within a short period to
confirm finds. Limit the run time of the
machine, if possible, and determine a
fault progression trend to prevent
additional component failure.
•Extreme(Days) – Consider shutting down the
equipment and taking repair action now
to avoid catastrophic failure. There is
likely other physical evidence of the
fault in terms of noise, higher bearing
temperatures or visible movement.
Retest the machine within a short
period to confirm finds.
To monitor the condition and degradation of the machine
over time, upload the diagnostic information to the Viewer
Software and track each fault’s severity. See the Viewer Software section for more details.
If the diagnosis shows extreme faults but you do not
sense any visual or thermal indication of the fault, revisit
Machine Setup and How to Measure Vibration. Verify that
you have the correct machine information and
measurements. Several factors can result in poor data
collection and inaccurate diagnoses:
The Tester collects data about vibration motion and
compiles this information in the time domain. Then, the
Tester transforms it into a frequency domain (spectra)
graph where the amplitude of the vibration signal is
graphed against the frequency or machine RPM.
Mechanical faults are detected at certain running speeds
or frequencies in the spectra. The algorithms identify, or
“cite” the abnormal vibration amplitude peaks (cited
peaks) at vibration spectra and then diagnose the
mechanical fault and severity.
For machines where the Tester found no faults, the
Details screen shows spectral data but not cited peaks.
To view fault information:
1. In the fault list, use the Dial to highlight the fault.
You can sort the records in memory to make it easier to
find a specific record.
1. Push . The options are:
• View by machine setup
• View by measurement date
• View by last diagnosis
