Line selection
Trigger waveform
When the specified trigger conditions are satisfied, the trigger waveform will be
displayed. The triggering time is the trigger point, generally on the middle of the
screen. When the trigger point is reached, the screen will display the waveform
from left to right over time. The user should set the following parameters before
using the trigger function.

Trigger mode
The trigger mode refers to the condition to update the contents on the
screen. It is divided into the Auto mode and Normal mode. In the Auto mode,
the displayed waveform will be updated when triggering occurs in the
suspension time; otherwise, the displayed waveform will be updated
automatically.
In the Normal mode, the displayed waveform will be updated in the case of
triggering and not updated in the case of no triggering.

Trigger source
The trigger source is used for generating trigger conditions.

Trigger edge
The edge refers to the change of the signal from low level to high level (rising
edge) or from high level to low level (falling edge). The edge used as a
trigger condition is referred to as the trigger edge.

Trigger level
The trigger level refers to the level which the trigger edge passes through.
If the signal of the trigger source passes through the set trigger level
according to the specified trigger edge, triggering occurs.
When "U￪" is selected for editing, you can adjust the trigger level using the
knob, number keys, or arrow keys. In this case, the trigger level can be
changed by rotating the knob and you can observe trigger level changes on
the screen.
Horizontal Control and Vertical Control

Vertical calibration
When V/grid or A/grid is selected, you can rotate the knob to set the voltage
or current range of each interval.

Horizontal calibration
When Time/grid is selected, you can rotate the knob to adjust the horizontal
scale (scanning speed). When the horizontal (time/scale) setting is changed
by rotating the knob, you can observe the change of time/scale on the
screen.

Trigger delay
You can adjust the trigger delay using the editing box (knob/directional
keys/numeric keys) or by horizontal sliding. The default trigger delay is 0,
Select the displayed curve, which is used to select
whether to display the voltage/current waveform of the
corresponding channel. Up to 4 oscillographic data
curves can be displayed.
