Operating Instructions
Basic Waveform Display and Adjustment
Upon powering on, the device will display waveforms. Use the touchscreen to interact with the display. You can adjust the vertical scale (Volts/Div) and horizontal scale (Time/Div) by tapping the corresponding channel settings (CH1, CH2) and time base settings on the top bar. Dragging waveforms vertically or horizontally allows for fine-tuning their position on the screen.

Trigger Modes
The oscilloscope supports three trigger modes to stabilize and capture specific events:
- Single Trigger: Captures a single event or transient signal, ideal for troubleshooting.
- Normal Trigger: Continuously captures and displays waveforms when the trigger condition is met.
- Automatic Trigger: Provides effortless continuous monitoring, even without a stable trigger event.
Select the desired trigger mode from the control menu. You can also set the trigger edge (rising or falling) and the trigger channel (CH1 or CH2).
