joystick right,Select the red box to Normal，press button，Normal
displayed in the upper left corner is set to normal trigger mode.The normal
trigger mode is to update this frame of waveform when the input signal
meets the trigger condition.For example, a burst signal,It can be captured
with single trigger and normal trigger,But the single trigger only captures
the first frame of signal,The normal trigger is to capture the last signal.

UTO(Auto trigger)：press button，Now in the menu page, move the
joystick up and down to select to trigger, move the joystick to the right,
and select toAuto，press button，When Auto is displayed in the upper
left corner, it is set to automatic trigger mode.Automatic triggering is the
most common,Also the simplest,Mainly used to measure periodic
signals,Such as sine wave, square wave, clock wave, PWM wave,
etc.,Regardless of whether the signal meets the trigger condition, the
waveform will always be updated.However, the waveform will not be
synchronized until the trigger conditions are met (without shaking left and
right).

.Comes with 1KHz square wave test signal：Comes with 1KHz square wave
test signal:Just connect the probe to the calibration end,You can see this
waveform on the screen,And based on this waveform parameter,Calibrate
the oscilloscope or probe.

0.Reference waveform：The reference waveform is to lock the waveform
displayed in the previous frame on the screen.The normally refreshed
waveform is not affected.Unlike a benchtop oscilloscope,The reference
waveform of this unit does not support other operations such as unfolding
or measuring.The reference waveform is useful for single-channel
