Key Points
Normal and Auto Mode. Use Normal trigger mode when you want the
oscilloscope to trigger only on a valid trigger. Use Auto trigger mode
when you want the acquisition to free-run in the absence of a valid
trigger event. Also, choose Auto when you want an untriggered,
rolling waveform at 500 ms/div or slower time base settings.
External Trigger. Use external trigger to trigger on a signal connected
to the DMM inputs. External trigger coupling is always DC. You can
choose either a 0.2 V or a 2 V trigger level.
