Getting Started
3.
Connect an oscilloscope to the X, Y, and/or Z axis test points on the measurement board. See
Determining the Axis of Vibration
for additional instructions.

4. Apply power to the board by connecting the micro-USB cable to a USB power source such as a
computer or USB charger.
5. AC couple the measurement channels on the oscilloscope and reduce the “V/div” to 50–100 mV. The
“V/div” may need to be adjusted later.
6. As the object vibrates, the acceleration should appear as a sine wave on the oscilloscope.
7. Convert the voltage to units of gravity. The conversion ratio is shown in
57 mV
