HI 813 PORTABLE SHAKER SYSTEMA built-in reference accelerometer is permanently attached to theshaker and armature so as to maximize accuracy between the referenceaccelerometer and the Transducer Under Test (TUT). The PSS provideslong term reliable performance over the frequency range of 30 Hz to 10kHz.The PSS is used for a number of applications including: Verification and calibration of vibration transducersand associated test systems.Verification of connector and cabling integrity.Verification of speed indicator measuring systems.Loads of up to 750 grams (26.5 ounces) can be mounted directly on theshaker head (reference accelerometer). For larger loads we recommendthat an external transducer suspension system be used. Under theseconditions the vibration waveform should be viewed on an oscilloscopeto aid in positioning the test transducer and shaker head to reduce distortion that might occur with very large weights.NOTE:Reference Accelerometer and shaker head are used interchangeably and mean thesame thing.TraceabilityThe moving part of the vibrator contains the reference accelerometerand along with the electronics is factory calibrated with traceability tothe National Institute of Standards and Technology (NIST). We recommend the built-in standard be re-calibrated once each year. The manualprovides a simple calibration check which can be performed more frequently. For a more detailed check, contact your local Hardy representative for more information.The HI-803 provides - 3% indicated value (IV) - 1 digit amplitudeaccuracy over the following ranges:MEASUREMENTFREQUENCY RANGEACCELERATION: g’s, 0 - PEAK 30 Hz to 3 kHzVELOCITY: ips, 0 - Peak30 Hz to 400 HzDISPLACEMENT: Mils, Peak - Peak30 Hz to 150 HzThe ability to provide performance at high frequency ranges in velocityand displacement are limited by several factors. The major factor is theamount of force available from the electrodynamic vibrator. Other factors include: 1-2Mechanical coupling of the test transducer and fixturing.Lateral forces of the test transducer and fixturing.Weight of the test transducer and fixturing.

Chapter 1 - Overview Reaction of the shaker mechanism to resonance.Accuracies of - 6% IV in the acceleration mode can be obtained overthe extended range of 10 kHz provided proper care is given whenmounting the test transducer to the shaker head.The MicrocomputerThe microcomputer manages the operation of the PSS by interpretingexternal commands entered from the frequency control buttons, monitoring operating parameters, measuring the built-in reference accelerometer and the transducer under test, performing calculations anddriving the displays. A significant benefit in having a microcomputer isits ability to run self tests to insure the PSS is functioning properly.FIG. 1-1 BLOCK DIAGRAM HI-813Typical entSourceAC Voltmeter orVibration MeterFIG. 1-2 CHECKING ACCLEROMETERS WITH BUILT-IN AMPLIFIERS1-3

Overtightening the mounting screw cancause bad readings.DI-103 Installationfor A & B AxesStep 4. Position the TUT for the A position. (See Fig. 3-2)FIG. 3-2 DI-103 A-AXIS POSITION WITH A ARROW POINTING DOWNStep 5. Screw the socket head bolt into the mounting bracket. Use atorque wrench and tighten the bolt that fastens the transducerto the bracket to 18 inch pounds. Do not overtighten.Step 6. Perform the tests for Axis A. This information can be found inthe documentation that comes with the transducer you aretesting. We use the DI-103 as an example. Make sure to referto the test documentation for the transducer you are currentlyusing. This information may differ from manufacturer to manufacturer. If you have more than one transducer to test, complete the test for the A Axis for all the transducers beforemoving on to Axis B or Axis C. This will save a lot of time.Step 7. When all the tests are complete, use the allen wrench andloosen the socket head bolt until you can rotate the transducerto the Axis B position. (See Fig. 3-3)3-3
