voltage:press”RUN” key to start the wait when there is a low level occurs, the devices
will automatically trigger and the trigger waveform record before and after a period of time
off.”HORI” key can change the horizontal position of the trigger position, and then you can
get different lengths, which can easily observe the waveform. See Figure 3-4
