# Start and Stop Acquisition

## Start Acquisition

When the program begins, no data is read from the QCM200 until you tell the program to begin. A red "STOPPED" button indicates that the program is not acquiring data. Clicking the red STOPPED button will cause the button to turn green, and the button will then read RUNNING. At that point, the program begins to get data from the QCM200 and display the results on the two charts (frequency and resistance).

## Stop Acquisition

In order to STOP data acquisition, press the green "RUNNING" button. The button will return to a red color and indicate that acquisition is "STOPPED".
