Horizontal POSITION
：
When adjusting the knob, the trigger point moves left and right
brelative to the center of the screen, and the waveform of all channels also move left and
right. The horizontal displacement value at the top of the screen will change in
real time. Press this knob to return the channel display position back to the horizontal
midpoint.
3) Horizontal SCALE Adjust the time base scale of all channels. You can see the waveform
is compressed or expanded in the horizontal direction on the screen during the process,
and the time base scale in the lower part of the screen changes in real time.
The time base scale has 1, 2 and 5 steps. Press the knob to quickly switch between main
and extensible window mode.
(3) Trigger Control
1) LEVEL: Turn clockwise to increase the trigger level and turn counterclockwise to decrease.
During the adjustment process, the trigger level value at the top right of

3) FORCE Force trigger button, press to force a trigger event once.
4) HELP Displays the built-in help system.
(4) Auto Setting
When this key is pressed, the oscilloscope will automatically adjust the vertical scale factor, sweep
time base, and trigger mode according to the input signals.
Note: When using the auto setting function, if the measured signal is a sin wave, the frequency is
required to be not less than 20Hz and the amplitude should be in the range of 20mVpp~120Vpp.
The auto setting function may not be valid without this parameter condition.
(5) Run/Stop
Press this key to set the oscilloscope’s operating state to "run" or "stop".
RUN state is indicated by green light.
STOP state is indicated by red light.
(6) Single Trigger
Press this key to set the trigger mode to “Single” and the yellow backlight will be on.
(7) Clear
Clear all waveforms on the screen. If the oscilloscope is in the "RUN" state, it will continue to
display new waveforms.
