Calibration
Each Slam Stick vibration data logger is supplied individually calibrated from the factory and
includes a NIST traceable calibration at 10g-peak, 100 Hz. Due to the fact that these units are
often used to measure harsh shock and vibration, the embedded accelerometer is often
subjected to excessive shocks, temperatures, radiation etc. These violent environments can
result in significant change in sensitivities and even permanently damage the unit. Therefore it is
wise to make periodic verification of the sensitivity calibration. This calibration frequency
depends on the application; but once every year is generally recommended for accelerometers.
The Modal Shop has a
nice article on the importance of calibration
. Remember that the user can
perform their own calibration of the Slam Stick too if cost is a concern, see Section User
Calibration Configuration.
NOTE:
The included calibration certificate is stored on the device in electronic form.
Sending back your unit for recalibration will provide you the confidence necessary to know that
your accelerometer remains accurate. If the sensitivity changed significantly the Slam Stick Lab
enables you to edit these coefficients for already recorded data. Mide will also update the
firmware on the device (if there is an update available) to reflect any improvements or bug fixes.
The calibrated device will be shipped back with a new roll of tape and mounting bolts too.
Visit our
and add the number of re-calibrations you require to your cart. Then
check out through the online ecommerce site and you will receive instructions. Typically the
turnaround time for recalibrations is less than 2 weeks.
Recording Data
Slam Stick is designed for easy plug-and-play operation, eliminating the need for complex analysis
equipment and extensive assembly time. A simple press of the Slam Stick membrane button
allows a user to collect shock & vibration data, instantly. The Slam Stick micro-USB port makes it
easy for users to transfer data onto their computer and the Slam Stick Lab software displays the
data for the user to view.
To start a recording on a Slam Stick X, press and release the “X” button (“S” on Slam Stick S and
“C” on Slam Stick C) located on top of the device. This action will tell a Slam Stick to begin a
recording or to “wake up” and wait for a trigger. Refer to the Setting Triggers section of this user
manual for more information on triggers. Whether a Slam Stick begins taking data or waits for a
trigger, the LED on the Slam Stick will flash. Table 10 provides an overview of the LED indication
during recording.
