case, change to NORM.
NORMAL
Captures a waveform every time a trigger signal is generated.
(normal sweep)
Sweep stops when no trigger signal is available. This ensures the
stable observation of the signals with a frequency of 25 Hz or less.
SGL
When a trigger signal is generated, captures a waveform only once.
(single)
To capture the waveform again, press the RUN/STOP button to
