Using

The icons on the toolbar are, from left to right:

Bright line Defeats the sync and single shot

Single shot Touch the trigger icon to get a trace

Trigger Touch for a trace

Sync polarity Reverses the sync polarity

Timebase Drops a submenu of timebase timings

Storage Does not clear the display between traces

Clear Clears the display

Left Moves the trace to the left

Right Moves the trace to the right

Start Moves the trace to the start

End Moves the trace to the end

Settings Just an About item

Touching the display will produce a vertical index line, which will show the value at that point. The value is arbitrary, as there is automatic gain control on the input so the trace does not get clipped. The position of the index can be finely adjusted by rolling the finger tip. The index can be removed by swiping it off to the left, or touching the Start icon.

In single shot mode the timebase may be changed to zoom in and pan left and right using the right and left icons.
