triggering condition detected in this mode, in which it will be
triggered compulsively when waiting for a specified period of
time without any triggering condition ignited When an invalid

oscilloscope will display the origin waveform without new
waveforms captured.
In this mode, the oscilloscope will detect a trigger and capture
a waveform at each time when the customer presses the
RUN/STOP key.
