(4) Automatic Setting
Press this key, the oscilloscope will automatically adjust the vertical scale, scan time base
and trigger mode according to the input signal to realize optimum waveform display.
Note
: Waveform auto setting function requires that the frequency of sine is no lower than
20 Hz; the amplitude must be at least 20 mVpp~120 Vpp. Otherwise, the waveform auto
setting function may be invalid.
(5) Run/Stop
Press this key set the operating state to "RUN" or "STOP".
In the "RUN" state, the key is illuminated in green.
In the "STOP “state, the key is illuminated in red.
(6) Single Trigger
Press this key to set trigger mode to “Single”, the key is illuminated in orange.
(7) Clear All
Press this key to clear all the recalled waveform on the screen. If the oscilloscope is in
RUN state, then keep refresh new waveform.

Press this key to save waveform as PNG format image and quick copy into USB device.
(9) Multipurpose Knob
Multipurpose
：
In menu operating, press the soft key of a menu and rotate the knob to
select a submenu under the menu. Then press the knob (that is, the select function) to
select the currently selected submenu.
(10) Jog Dial Knob
For numerical parameter that the setting range is large, this knob can be used to quick
adjustment. Rotate clockwise (anticlock wise) to increase (decrease) numerical value;
inner layer can be fine tunning, outer layer can be coarse tunning. Such as, rotate this
knob to quickly locate the waveform frame that need to recall. This knob also can be used
to set parameter like trigger holdoff time, pulse width setting and slope time.
