2. Horizontal control
a. HORI MENU : Displays extended window,
independent time base and trigger hold-off.
b. Horizontal POSITION : When adjusting the knob,
the trigger point moves left and right relative to
the center of the screen, and the waveforms 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.。
c. Horizontal SCALE : Adjust the time scale of all
channels. You can see the waveform is compressed
or xpanded 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 step is 1-2-4. Press the
knob to quickly switch between the main window
and the extended window.
3.Trigger Control
a. MODE : Press this key to switch the trigger mode
to Auto, Normal or Single, and the corresponding
backlight of the current trigger mode will turn on.
b. LEVEL : Turn clockwise to increase the level, turn
counterclockwise to decrease the level. During the
adjustment process, the trigger level value
at the top right of screen will change
Press the knob to quickly return the in real time.

c. TRIG MENU : Displays the contents of the trigger
menu. For details, see "Trigger setting system".
d. FORCE : Force trigger button, press this button to
force a trigger.
e. HELP : Displays the built-in help system contents.
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 sine
wave, the frequency is required to be not less than 20Hz and the amplitude
should be in the range of 20mVpp ~ 120Vpp. If this parameter condition is
not met, the auto setting function may not be valid.
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 orange
backlight will be on.
7.Clear All
Clears all waveforms on the screen. If the oscilloscope is in the
"RUN" state, it will continue to display new waveforms.
8. Print Screen
Press this key to quickly copy the screen waveforms to a USB storage
device in BMP bitmap format.
9. Multipurpose Knob
Intensity: In non-menu operation, turn this knob to adjust the
brightness of the waveform display. The brightness adjusting range
is 0% ~ 100%. You can also press the DISPLAY →waveform
brightness to adjust it. Multipurpose: Turn the knob to select the
sub-menu, then press the knob to confirm selection.
