1. OVERVIEW
The METRIX Model HI-903 Portable
Vibraon Calibrator provides a eld
tested method for on-the-spot dynamic
vericaon of accelerometers, velocity
pickups and non-contact displacement
transducers. Oponal mounng xtures
and hardware needed to connect
transducers to the HI-903 mounng
plaorm are available upon request.
A closed-loop control algorithm provides
enhanced stability and accuracy of
frequency and amplitude levels.
The HI-903 incorporates a built-in
sine wave oscillator, power amplier,
electrodynamic shaker, NIST traceable
reference accelerometer, digital display,
and internal memory. The HI-903 is
completely self-contained and operates
on baery or AC power.
The built-in reference accelerometer
is aached permanently to the shaker
armature, maximizing the accuracy
between the reference accelerometer
and the test transducer. The HI-903 is
designed to provide long-term reliable
performance over the frequency range of
7 Hz to 10 kHz. The HI-903 can be used
for a variety of applicaons that include:
• Vericaon and calibraon of
vibraon transducers and related
vibraon test systems
• Vericaon of connector and cabling
integrity
Conrm machine vibraon alarm trip
points are set properly and ensure
end-to-end funconality of vibraon
monitoring systems.
Notes
• Loads of up to 800 gram (28.3
oz) can be mounted directly to
the HI-903 mounng plaorm.
Larger loads may be applied to the
plaorm, however, if prolonged
tesng of a heavy load is planned,
we recommend using an external
transducer suspension system.
Under these condions the vibraon
waveform should be viewed on the
oscilloscope to aid in posioning
the test transducer and plaorm to
reduce distoron that can occur with
very heavy weights.

2. BASIC OPERATION
For the basic operaon of the HI-903, a vibraon sensor and appropriate cable
are needed. Typically the HI-903 is used as a vibraon excitaon source and as a
readout device with the vibraon sensor connected to the HI-903’s Test Sensor BNC
Input. Alternavely, the HI-903 unit can be used to test dierent types of vibraon
equipment (i.e. a vibraon meter or vibraon monitoring system), in which case
the sensor will be directly connected to the vibraon measurement equipment and
the HI-903 is used just as a controlled excitaon source.
Test Setup
1. Mount your sensor to the HI-903 mounng plaorm
• The HI-903 sensor mounng plaorm is threaded for a ¼-28 stud. Select
an appropriate adaptor for mounng the sensor.
• While ghtening the sensor, secure the HI-903 mounng plaorm with
the supplied wrench to prevent damage from torque
2. Connect sensor under test (SUT) to “Test Sensor In.” Make sure that
connecons are secure.
3. Power the unit ON by pressing and holding the FREQUENCY dial for 3 seconds.
NOTE: It is good pracce to perform calibraons on baery power. Disconnecng
from line power ensures a power surge will not cause the calibrator to power down
during test. If excess current is detected during use, the portable calibrator shuts
down to prevent damage.
Selecng Input Mode
4. The HI-903 can accept ICP® as well as AC voltage and AC current output
sensors. Press and hold the AMPLITUDE dial to select between ICP®, Voltage Mode
or Modulated Current mode. Modulated Current mode is only available if the 9110-
MC rmware opon is ordered, otherwise user will not see this mode as an opon.
Note: ICP® (or IEPE) mode sensors are the most popular type of accelerometer
transducers and require a 2 mA to 20 mA constant current supply to operate.
The HI-903 unit supplies the necessary constant current to power this class of
sensors. Voltage output sensors are typically moving coil velocity sensors but
can also be the voltage output of a signal condioner associated with any type
of vibraon transducer such as the output from the probe driver in a proximity
probe system. Refer to the Sensor Signal Measurement Electronics (SUT Input
Characteriscs and Consideraons) for details.
Seng the Frequency and Amplitude Units
5. Select the correct Frequency Units for your test by pressing the FREQUENCY
dial to enter into the CALIBRATION OPTIONS menu:
• Use the FREQUENCY dial to highlight TEST SETTINGS then press.
• Within the Test Sengs Menu rotate the FREQUENCY dial to
highlight FREQUENCY UNIT then press to toggle between Hertz and
CPM.
6. Select the correct Amplitude Units for your test by pressing and releasing the
AMPLITUDE dial. The following opons are available:

7. Select the desired vibraon amplitude and frequency for tesng by turning the
AMPLITUDE and FREQUENCY dials clockwise to increase or counter clockwise to
decrease the seng.
•Slow Turns – sengs will increase or decrease by single steps
•Fast Turns – sengs will increase or decrease by larger increments
Record and Save Calibraon Points
8. Once the frequency and amplitude are set to desired values, with the le
menu set to “Save Point,” press the FILE dial to store the calibraon data point.
9. Repeat steps 7 through 9 to set the frequency and amplitude to increment to
the next calibraon data point and save.
Compleng and Storing Record to Memory
10. Once all data points have been saved in a record and record is complete, rotate
FILE dial and press it to select “End Record.”
• The screen will prompt with:
11. Rotate the FILE dial to “Edit” to enter the model number, serial number and
axis. The FILE menu for this screen also includes the tools “Next” and “Back.”
• Push the FILE dial to choose “Next,” which goes to the next save
screen.
12. To “Save” the record without inpung an annotaon, press the FILE dial two
more mes.
13. Rotate the FILE dial to “Edit” and press to store any annotaons or addional
notes (such as technician inials, etc):
• Turn the FILE dial to the le and right to select each individual leer
or number you wish to input as part of an annotaon. Push the FILE
dial to save each character.
• Rotate the FILE dial and select “Save.” This will save all data points in
the listed record number. The record number shown on the screen

Transfer Records to USB Flash Drive
14. Rotate FILE dial and press to select “Tools.”
15. Rotate FILE dial and press to select “USB Menu.”
• A USB ash drive must be connected to the unit. The USB must be
formaed to FAT32. You can use the HI-903 or a PC to format the
ash drive.
16. To copy all data points and records to a USB Flash Drive, rotate FILE dial and
press to select “Copy All Records.”
• This will leave current records on unit memory and also create a
copy on the USB.
17. To move all data points and records to USB, rotate FILE dial and press to select
“Move All Records.”
• This will remove current records on unit memory and move onto the
USB.
Note: The USB hardware may not always recognize a USB ash drive if it is plugged
into the USB port while the HI-903 is in sleep mode. Metrix recommends connecng
the USB drive while the HI-903 is on and operaonal.
Powering O
18. Suggested Best Pracce: Before powering the unit OFF, reduce the vibraon
amplitude. The HI-903 retains the sengs used prior to shutdown when it
is powered back ON. Reducing the amplitude prior to shutdown ensures the
sensor under test will not be jarred when the HI-903 is powered ON.
19. Power the unit OFF by pressing and holding the FREQUENCY dial for
approximately 3 seconds.
• To preserve baery charge, the HI-903 will automacally power o
aer 20 minutes of inacvity when not plugged in to the charger.
Aer Tesng
20. Suggested Best Pracce: Plug the HI-903 into an AC power source when not in
use. This will ensure the baeries are fully charged for your next test and also
help to maximize the lifespan of the baeries.
21. Periodic calibraon checks are recommended:
• A dedicated “vericaon sensor” can be used to check the system
readings and results. By using a dedicated sensor, you can ensure
that the system is providing the same result during each test. Metrix
oers Model 9105D for this purpose. (The 9105D includes a transfer
standard reference accelerometer and ICP sensor signal condioner,
for system vericaon of portable vibraon calibrators).
• The HI-903 should be returned to Metrix for regular recalibraon
(recommended annually - Service Code 9100-CAL01) or for any
maintenance or repair. The most current factory calibraon date or
the calibraon due date is displayed on the LCD screen during the
HI-903 boot up sequence. The default due date is set for 12 months
aer the last factory calibraon, but the calibraon interval can be
user dened to be anywhere from 1 to 72 months, or set up to never
expire.
• NOTE: The aforemenoned Model 9105D allows users to duplicate
Metrix’s calibraon process without returning the shaker to the
factory.

Report Generaon Workbook
Calibraon data can be saved into the HI-903’s internal memory and easily
exported to a personal computer using a USB Flash Drive.
The HI-903 Portable Vibraon Calibrator includes a pre-formaed USB Flash
Drive with a Microso Excel Report Generaon Workbook for the creaon of
customizable calibraon cercates. The Excel le provides an intuive interface
which allows a user to create and print a calibraon cercate with just a few
mouse clicks. In order to use the le, make sure macros are enabled, otherwise
Excel won’t be able to load data and create the cercates.
The Excel workbook consists of the following worksheets or tabs:
• FRData – Use this tab to create a frequency response cercates in just 2
steps:
1. Clicking on Import Data from File buon prompts the user to select and import
a .pvc calibraon data le previously created by the HI-903
2. Once data is loaded into the table, click View Cercate to see and print a
calibraon cercate containing the frequency response data (the reference
frequency for the calibraon cercate is 100Hz and can be changed by the
user as needed)
Note: If tesng a charge-mode accelerometer and calibraon cercate
in pC units is desired, click the box at top le of the FRData tab and enter
the sensivity of the charge amplier in the “mV/pC” box located at cell
D8. See the secon “Calibrang Charge-Mode Accelerometers” for more
informaon.
• LINData – Use this tab to create linearity response cercates. The worksheet
applies linear regression to interpolate the data. The Max Linearity is calculated
for the worst deviaon of a parcular point from the best-t straight line (BFSL)
of all tested points. The table also displays the specic results at each test level.
The LINData worksheet has 2 tables. The le table should be used for creang
dynamic linearity data calibraon cercates in just 2 steps:
1. Click on Import Data from File to select and import a .pvc calibraon data le
previously created by the HI-903
2. Once data is loaded into the table, click View Cercate to see and print a
calibraon cercate containing the linearity response data. The worksheet
expects the data points to be taken at the same frequency (speed). A checkbox
opon labeled Set Y-intercept to zero is available to force the interpolaon to
go through the origin point.
The right table in the LINData worksheet is used to create a DC proximity probe
curve or linearity cercate for 4-20 mA vibraon transmier. Creang a DC
proximity probe curve requires the proximity probe adaptor kits and a DC
voltmeter (not included). Creang a linearity cercate for a 4-20 mA vibraon
transmier requires DMM set to DC current input. A 24 VDC power supply may
also be needed:
1. Select the appropriate vibraon scale (Acceleraon, Velocity or Displacement)
by clicking in cell H12 and selecng from drop down menu.
2. Select the appropriate units (g’s pk, g’s RMS, m/sec2 pk, m/sec2 RMS, in/sec pk,
in/sec RMS, mm/sec pk, mm/sec RMS, mils p-p or µm p-p) in cell H13. Make
sure cell H12 is set to the right scale rst.
3. Enter known amplitude and output for the rst test point next to “Starng
Point” and repeat for each addional test point moving down the table.
Once data is entered into the table, click View Cercate to see and print a
calibraon cercate containing the linearity response data.
• FRCert - Displays the frequency response calibraon cercate using the

Calibraon Route
Firmware Opon: HI-903 CALROUTE
Model HI-903 must be ordered with rmware opon 9110-CALROUTE for the
Calibraon Route features to be available. This rmware can be added at any me.
Contact Metrix for ordering and installaon informaon.
The Calibraon Route rmware allows users to create and run semi-automated
frequency response and amplitude linearity tests for vibraon sensors on model HI-
903 with instant pass/fail nocaon. Tests or “routes” are created in the Report
Generaon Workbook then uploaded to the HI-903 via supplied USB drive. Once
uploaded the test is acvated. But the test can also be de-acvated at any me,
pung the HI-903 back into manual operaon mode. When a Calibraon Route
is acve the HI-903 can only adjust to the pre-dened amplitude and frequency
points that have been programmed.
Creang A New Test (Route)
Version 2010 or later of Microso Excel® is required for the CalRoute features
in Report Generaon Workbook to operate correctly. Drop-down arrows for
frequency and amplitude units may not appear if using older versions of this
soware.
1. Open the Report Generaon Workbook (version 3.0.2 or later required)
using Microso Excel®
2. At boom, select the Route Creator tab
3. Route Name: Enter the name of the test in cell B7 next to “Route Name”.
When the test le is created and saved the le name will be this value
followed by “_Route.pvc”.
4. Frequency Unit: Use the drop down arrow to choose the frequency unit
(Hertz or CPM) in cell B8. One cannot toggle between Hertz and CPM
during the test.
5. Amplitude Unit: Use the drop down arrow to choose the amplitude unit
(g pk, g RMS, m/sec2 pk, m/sec2 RMS, in/sec pk, in/sec RMS, mm/sec pk,
mm/sec RMS, mils p-p or µm p-p) in cell D7.
6. Amplitude: If desired, enter the amplitude for all test points in cell B9 next
to “Amplitude”. This is useful for a frequency response test where all test
points will have the same amplitude value. If creang a linearity test leave
this cell blank since the amplitude values will change for each test point.
Doc# 100928 • HI-903-Shaker • October 2017-RevA Page 10 of 33
7. Sensor Type: Use the drop down arrow in cell F7 to select the sensor type
(ICP®, Voltage or Modulated Current).
8. Sensor MN: if desired, enter the sensor model number in cell F8. This
is oponal. The sensor model number that is entered will print on the
calibraon cercate. It can be changed at any me. If the model number
is not consistent leave this cell blank.
9. Lower Bound: in cell D8 enter the minimum sensivity value for the
sensor under test at each test point that will pass calibraon test. For
example, the minimum acceptable sensivity for 100 mV/g accelerometer
with +/- 5% sensivity tolerance is 95 mV/g, thus lower bound would be:
95.00.
10. Upper Bound: in cell D9 enter the maximum sensivity value for the
sensor under test at each test point that will pass calibraon test. For
example, the maximum acceptable sensivity for 100 mV/g accelerometer
with +/- 5% sensivity tolerance is 105 mV/g, thus upper bound would be:
105.00.
11. Press Table Auto-Fill. The grey cells in the table will automacally
populate with the values chosen in steps 3-10. All cells will populate. The
table is capable of creang a 30-point test. But any number of test points
can be programmed. Before creang the route le user must delete values
in cells for test points that should not be created (see example).
12. Enter the desired Frequency values for each test point in column A
beginning with cell A13. The test will be conducted in the exact order as
programmed. The rst test point will be as programmed in row 13; the
next will use row 14 values and so on.
a. The HI-903 can only simulate vibraon in CPM values that are
mulples of 60. I.e. 1800 CPM, 3600 CPM, 4200 CPM, etc. If a
value is entered that is not a mulple of 60, the HI-903 will adjust
down to the nearest CPM value that is a mulple of 60.
b. Example: 1900 CPM is entered as a test point. The HI-903 will
adjust to 1860 CPM and 1860 CPM will be displayed.
13. Enter the desired Amplitude values for each test point in column B
beginning with cell B13. Skip this step if all amplitude values have been
automacally populated using the Table Auto-Fill buon.
14. Modify any individual test point as desired. For example, most
accelerometers have a wider sensivity tolerance at extreme low and high
frequencies. User may wish to expand the upper and lower bounds for
certain test points.
15. Delete undesired test points. For example, a 10-point test only requires
rows 13-22. The Table Auto-Fill feature saves typing but one must delete
data from cells that are not needed. For a 10-point test rows 23-42 should
be blank thus they can be highlighted and cleared.
16.Press Create Route File. A .pvc le will be created, save this le to the USB
drive in the Calibraon_Route folder.
a. When prompted to save, open the USB Disk
b. Open the METRIX_PVC folder
c. Open the Calibraon_Route folder
d. Press save
