on the edges of the control indicate where the ROI window boundaries are set within the total
measurement time. When the ROI Timeline control is activated the rest of the Main Panel will display
only data from the selected window (to see the ROI in action, see Figure VI-6). Additionally, any reports
generated or data exported will contain only data from the ROI. This is useful for eliminating unwanted
transient signals, such as radon or moisture, without having to do another run. The ROI can be hidden
using the button indicated as j* in Figure VI-1. You can remove the ROI selection either by sliding the
bars back, double-clicking inside the ROI control window, hitting Ctrl+A, or going to the View menu and
selecting “Auto-scale”.
