คำแนะนำการใช้งาน

การดำเนินงานทั่วไป

The device features a 2.8-inch HD color screen and intuitive button controls. The main power button is located on the front panel. Navigation buttons (up, down, left, right, enter) are used to select modes and adjust parameters. The 'MENU' button accesses settings, and 'SAVE' allows for waveform screenshot capture.

โหมดออสซิลโลสโคป

To enter Oscilloscope mode, ensure the appropriate probes are connected to the CH1 and/or CH2 inputs. Use the 'AUTO' button for automatic waveform adjustment. Adjust vertical sensitivity (V/div) and time base (s/div) using the navigation buttons. The device supports various trigger modes (Auto/Normal/Single) and trigger types (Rising edge, Falling edge) for stable waveform display.

• หัววัดการเชื่อมต่อ: Connect the 10X probe or crocodile clip probe to the CH1 or CH2 BNC connectors. Ensure proper grounding.
• การปรับพารามิเตอร์: Use the navigation buttons to adjust vertical scale (voltage per division) and horizontal scale (time per division).
• ทริกเกอร์: Set the trigger level and mode to stabilize the waveform. The 'AUTO' function can quickly set optimal display parameters.
• Waveform Saving: Press the 'SAVE' button to capture a screenshot of the current waveform. Saved images can be reviewed on the device or exported to a computer via USB.
