In our previous oscilloscope projects, we have acquired data continuously: after clicking the Run button, the oscilloscope continuously acquired and displayed data until the Stop button was clicked.
Sometimes it is desirable to obtain a single set of data. This is often the case when our data are the result of some event; for example, we might want to measure sound levels resulting from an explosion. We would really just like to measure the data beginning from the time of the explosion, and terminate data acquisition a short time after the explosion. We can do this with our scope by using single sequence acquisition.
In this project, we will acquire vibration data from the piezoelectric sensor in our parts kit.

Connect the terminals of the sensor to the terminals of channel 1 of the oscilloscope.
Insert the leads of the piezoelectric sensor into your breadboard. The leads of the sensor should be in different rows of the breadboard.
Connect the terminals of channel 1 (1+, 1-) to the sensor's terminals.
Open WaveForms™ to view main window.
Click on the Scope icon to open the oscilloscope instrument.
Click on to start acquiring data. The trigger indicator just above the display window should read , indicating that the scope is ready to begin acquiring data once the trigger condition is met.
