The Auto Scale function examines all channels for signals and displays corresponding
waveforms. Auto Scale determines the trigger source according to the following
conditions.
 If multiply channels get signals, the oscilloscope will use the channel with
the lowest frequency signal as the trigger source.
 If no signals are found, the oscilloscope will use the lowest-numbered
channel displayed in Auto Scale as the trigger source.
 If no signals are found and no channels are displayed, the oscilloscope will
display and use Channel 1 as the trigger source.
When you use the Auto Scale function and the oscilloscope determines that the signal
is similar to a sine wave, the oscilloscope displays the following options.
