IMI Sensors: A PCB Piezotronics Div 699A07 User Manual
MAN-0192 rev A Page 4 of 39 800-959-4464
Introduction
Welcome
Thank you for choosing IMI Model 699A07.
The IMI Model 699A07 Portable Vibration Calibrator provides a field tested method
for on-the-spot dynamic verification of accelerometers, velocity pickups and non-
contact displacement transducers. Optional mounting fixtures and hardware
needed to connect transducers to the 699A07 mounting platform are available upon
request.
A closed-loop control algorithm provides enhanced stability and accuracy of
frequency and amplitude levels.
The 699A07 incorporates a built-in sine wave oscillator, power amplifier,
electrodynamic shaker, NIST traceable reference accelerometer, digital display, and
internal memory. The 699A07 is completely self-contained and operates on battery
or AC power.
The built-in reference accelerometer is attached permanently to the shaker
armature, maximizing the accuracy between the reference accelerometer and the
test transducer. The 699A07 is designed to provide long-term reliable performance
over the frequency range of 5 Hz to 10 kHz. The 699A07 can be used for a variety
of applications that include:
• Verification and calibration of vibration transducers and related vibration
test systems
• Verification of connector and cabling integrity
• Confirm machine vibration alarm trip points are set properly and ensure
end-to-end functionality of vibration monitoring systems.

Cautionary Notes
• Loads of up to 800 gram (28.3 oz) can be mounted directly to the
699A07 mounting platform. Larger loads may be applied to the platform,
however, if prolonged testing of a heavy load is planned, we recommend
using an external transducer suspension system. Under these
conditions the vibration waveform should be viewed on the oscilloscope
to aid in positioning the test transducer and platform to reduce distortion
that can occur with very heavy weights.
• The 699A07 should always be operated on a stable, flat surface.
