The use of EVAL-ADXL335Z

Hi,I use accelerator(EVAL-ADXL335Z) to measure acceleration of the actuator in the moment of turning back.

The structure of the experiment is in the following picture.

 

 

 

 

Then I use Labview software to control the actuator's movement.The actuator moves at the constant speed and turns back in the terminal.The moving amplitude of the actuator is 40mm.

The waveform of Z-axis output is captured by oscilloscope's probe.

The waveform is in the following picture.


 

 


 

I think the waveform represents the displacement not acceleration of turning back.

I don't know which part is wrong in the measurement.

Please give advice to help me.

Thank you.
