The device uses a USB Port for on the fly configuring, charging and downloading of data. Simple configuration software allows users to tailor the device to their specific needs. The configuration options include an adjustable delay time before each measurement, different measurement durations, and a trigger based on a pre-determined acceleration level. Free analysis software allows for complete vibration characterization enabling the user to determine the frequency content of their given vibration. The Slam Stick™ can be used for many different applications including energy harvesting vibration characterization, modal surveys and equipment monitoring. Simply configure the device for your application, mount the device on your vibrating structure, hit the button and download the data to your computer.

The plots above represent the distribution of noise in the recorded data for each axis. This distribution is approximately Guassian, with the majority of samples falling very close to the correct value and less frequent outliers falling further from the correct value. This distribution is typical of random noise present in any measurement. 0.4 1 10 10 2 10 3 10 4 Frequency (Hz) Frequency roll off data was taken by exciting the Slam Stick at a constant amplitude (1 gee in this case) over a range of frequencies from 10 Hz to 3200 Hz. The measured vibration amplitude from the Slam Stick was then plotted versus frequency. Note that the roll off is severe after ~500 Hz in the Z axis. This roll off occurs at ~300 Hz in the X and Y axes. Different devices performed differently after this frequency and amplitude data should not be trusted when above this frequency. Frequency data is not impacted by this roll-off. PN: LOG-0001 | REVISION No. 004 | DATE: 10-24-2014 | Web: www.mide.com | Email: service@mide.com 3 of 3
