bottom right corner of the screen, e.g. . It indicates that the
trigger type is rising edge, the trigger source is CH1, the trigger coupling is DC,
and the trigger electrical level is -20.0mV.
The description of the trigger system setting menu is as follows:

Set Channel 1 as the source trigger signal.
Set Channel 2 as the source trigger signal.
Coupling
AC
DC
Set to prevent DC component from passing
through.
Set to allow all components to pass through.

Waveforms can be acquired without detecting
trigger conditions.
The waveform is acquired only when the trigger
conditions are met.
When a trigger is detected, a waveform is sampled
and then stopped.

Trigger electrical level: The amplitude level that the signal must cross when
setting the waveform acquisition. Press the Trig/△ key to enter the trigger
menu, and press the Up or Down key to move the trigger electrical level up
and down.
