How to set trigger

Trigger determines when the oscilloscope starts to collect the data and
display the waveform. Once it is set properly, it can convert unstable
display into the meaningful waveform.
When the oscilloscope starts to collect the data, enough data are used to
draw the waveform at the left of the trigger point. The oscilloscope
continuously collects data while waiting for the trigger conditions. When a
trigger is detected, the oscilloscope will continuously collect enough data
to draw the waveform at the right of the trigger point.
There is one knob and two function menu keys in the Trigger Control
Area.
Trigger Level: Turn this knob to set the signal voltage of corresponding
trigger point and press this knob to make the trigger level at
the vertical midpoint of the trigger signal amplitude.
Forced Trigger: Generate a trigger signal forcibly, mainly used in the
Trigger Menu: Trigger menu keys.
