The Modal Shop, Inc.9100D User ManualIntroductionWelcomeThank you for choosing TMS Model 9100D.The TMS Model 9100D Portable Vibration Calibrator provides a field-tested methodfor on-the-spot dynamic verification of accelerometers, velocity pickups and noncontact displacement transducers. Optional mounting fixtures and hardware neededto connect transducers to the 9100D mounting platform are available upon request.The 9100D incorporates a built-in sine wave oscillator, power amplifier,electrodynamic shaker, NIST traceable reference accelerometer and digital display.The 9100D is completely self-contained and operates on battery or AC power.The built-in reference accelerometer is attached permanently to the shakerarmature, maximizing the accuracy between the reference accelerometer and thetest transducer. The 9100D is designed to provide long-term reliable performanceover the frequency range of 7 Hz to 10 kHz. The 9100D can be used for a variety ofapplications that include: Verification and calibration of vibration transducers and related test systemsVerification of connector and cabling integrityVerification of speed indicator measuring systemsCustomer SupportThe Modal Shop, Inc. is a PCB Group Company, and we are 100% committed to thePCB Group’s pledge of ‘Total Customer Satisfaction.’ If at any time you havequestions or problems with the 9100D system, please contact an ApplicationEngineer at The Modal Shop:Telephone:Toll Free:Fax:Email:513-351-9919800-860-4TMS ary NotesMAN-0103 rev C Loads of up to 800 grams (28.3 ounces) can be mounted directly to the 9100Dmounting platform. Larger loads may be applied to the platform, however, ifprolonged testing of a heavy load is planned, we recommend using an externaltransducer suspension system. Under these conditions the vibration waveformshould be viewed on the oscilloscope to aid in positioning the test transducerand platform to reduce distortion that can occur with very heavy weights. The 9100D should always be operated on a stable, flat surface. The 9100D is designed for field test applications but care must be taken tomaintain the integrity of the mounting platform assembly. Hearing protection recommended when operating the 9100D.Page 4 of 24800-860-4867

The Modal Shop, Inc.9100D User Manual9100D Operation GuideBasic OperationTest Setup1. Mount your sensor to the 9100D mounting platform. The 9100D sensor mounting platform is threaded for a ¼-28 stud. Select anappropriate adaptor for mounting the sensor.While tightening the sensor, secure the 9100D mounting platform with thesupplied wrench to prevent damage to the shaker from torque.2. Connect sensor signal conditioner and readout device as necessary. Make surethat connections are secure.3. Power the unit ON by pressing and holding the FREQUENCY dial for 3seconds. Setting the Frequency4. Select the desired frequency for testing by turning the FREQUENCY dialclockwise to increase or counterclockwise to decrease. Slow Turns – setting will increase or decrease by single steps Fast Turns – setting will increase or decrease by larger increments5. Select your preferred Frequency Unit for your test by pressing and releasing theFREQUENCY dial. Hertz CPMNote: Pressing the dial one more time enables the External Source Input (seepage 10). Pressing the dial again allows you to cycle through the frequencychoices.Setting the Amplitude6. Select the correct Amplitude Units for your test by pressing and releasing theAMPLITUDE dial. The following options are available:Accelerationg’s pkg’s RMS2m/s pk2m/s RMSVelocityin/s pkin/s RMSmm/s pkmm/s RMSDisplacementmils p-pµm p-p7.

The Modal Shop, Inc.9100D User ManualCompleting the Test8. Verify that the level indicated on the 9100D is the same as the level beingshown on the readout of the sensor under test.9. Before powering the unit OFF, reduce the vibration amplitude. The 9100Dretains the settings used prior to shutdown when it is powered back ON.Reducing the amplitude prior to shutdown ensures the sensor under test will notbe jarred when the 9100D is powered ON.10. Power the unit OFF by pressing and holding the FREQUENCY dial for 3seconds. To preserve battery charge, the 9100D will automatically power off after 20minutes of inactivity when not plugged in to the charger.After Testing11. Plug the 9100D into an AC power source when not in use. This will ensure thebatteries are fully charged for your next test and also help to maximize thelifespan of the batteries.12. Periodic calibration checks are recommended. A dedicated “verification sensor” can be used to check the system readingsand results. By using a dedicated sensor, you can ensure that the system isproviding the same result during each test. The 9100D should be returned to The Modal Shop for regular recalibration(recommended annually - Service Code 9100-CAL01) or for anymaintenance or repair. The most current factory recalibration date isdisplayed on the LCD screen during the 9100D boot-up sequence.Definition of Frequency UnitsMAN-0103 rev C Hertz (Hz) is defined as the number of periodic cycles per second and it is astandard unit for measuring signal frequency. CPM stands for Cycles Per Minute. CPM is commonly used for testingindustrial sensors that monitor rotational vibration. 1 Hz 60 CPMPage 8 of 24800-860-4867
The Modal Shop, Inc.9100D User ManualDefinition of Amplitude UnitsFigure: Sinusoidal Wave Root Mean Square (RMS) is a calculation that takes the square root of theaverage of the squared amplitudes from a set of data. This type ofmeasurement takes all amplitudes of a signal into account rather than justone, making it an accurate tool for an overall calculation. Peak (pk) bases calculations on the highest value of the signal generatedduring testing. For a sinusoidal wave (as is produced by the 9100D), thepeak value is calculated by RMS* 2. The 9100D does not measure a truepeak value, but instead estimates the value mathematically based upon theRMS value. Peak to Peak (p-p) is a calculation of the difference between the highestpositive peak and the lowest negative peak of a recorded sine wave. Thep-p value is calculated as two times the peak value. Gravitational acceleration (g) is the acceleration experienced naturally byobjects in earth’s gravitational field. It is approximately equal to 9.806652m/s .Mounting BasicsConnecting Sensor to 9100D Platform1. Mating surfaces of the mounting platform and sensor should be flat, parallel andfree of dirt, paint, epoxy, scratches, etc.2. Threads in platform, sensor and adaptor (if needed) must match to ensure aproper fit and that testing is free of errors. Clean any worn threads with a tap ordie and coat them in a silicone grease for best results.3. An adaptor may be needed to connect the sensor to the armature. The 9100Dplatform requires a ¼-28 thread.4. A silicone grease can be applied to the mating surfaces and threads to ensuregood mechanical coupling. This is particularly important when testing at highfrequencies.MAN-0103 rev CPage 9 of 24800-860-4867
The Modal Shop, Inc.9100D User ManualTightening and Loosening Connections1. When tightening or loosening the connection between the sensor and the9100D mounting platform, secure the mounting platform with the suppliedwrench.2. It is important to keep sensors and fixtures centered and straight whenattaching them to the 9100D mounting platform. This will ensure a stable,even connection and eliminate potential alignment issues.External Source InputAs an option, it is possible to drive the 9100D by using an external signal source ora function generator. First, connect a signal source to the External Source BNCInput located on the top right corner of the unit. To enable the External SourceInput, press the FREQUENCY dial to toggle through the units until the Ext Sigoption is selected on the display.1. When in external signal mode, the vibration amplitude is measured anddisplayed on the screen, however, the frequency and amplitude of the shakeris controlled by the external source, not by the 9100D. The frequency of theinput signal is not displayed on this mode.Do not exceed 1V RMS! Overdriving the unit may cause clipping, unwanteddistortion and damage to the unit.Monitor Reference OutputThe 9100D is controlled by an internal shear mode quartz reference accelerometer.The voltage output of the reference accelerometer can be monitored through theavailable Monitor Reference BNC Output by connecting it to a readout device (e.g.voltmeter or oscilloscope).MAN-0103 rev CPage 10 of 24800-860-4867
