Term interpretation
■ Auto:
This sweep mode allows the scope meter to acquire waveforms even when it does
not detect a trigger condition. If no trigger condition occurs while the scope meter is
waiting for a specific period (as determined by the time-base setting), it will force itself
to trigger.
When forcing invalid triggers, the scope meter cannot synchronize the waveform,
and the waveform seems to roll across the display. If valid triggers occur, the display
becomes stable on the screen. Any factor results in the un-stability of waveforms can
be detected by Auto Trigger, such as the output of Power supply.
NOTE: When horizontal control is set under 50 ms/div, Auto mode allows the
oscilloscope not to capture trigger signal.
■ Normal:
The Normal mode allows the scope meter to acquire a waveform only when it is
triggered. If no trigger occurs, the scope meter keeps waiting, and the previous
waveform, if any, will remain on the display.
■ Single:
In Single mode, after pressing the RUN/STOP key, the scope meter waits for trigger.
While the trigger occurs, the scope meter acquires one waveform then stop.
