To turn on a new channel, math, memory, or zoom trace, drag any descriptor box of the same type to the Add New ("+") box. The next trace in the series will be added to the display at the default settings. It is now the active trace.
If there is no descriptor box of the desired type on the screen to drag, touch the Add New box and choose the trace type from the pop-up menu.
To turn on the Measure table when it is closed, touch the Add New box and choose Measurement.
