5. Assembly Instructions (Setup)

This kit requires soldering. Ensure you have the necessary tools (soldering iron, solder, wire cutters, multimeter) and basic soldering skills before beginning. Always refer to the provided 'Part List' and circuit diagram for component placement.

5.1 Component Identification

Before soldering, identify all components. Use a multimeter to verify resistor values, as shown in Video 1 (0:28-1:08).

5.2 Soldering Components

Solder the through-hole components onto the main circuit board according to the provided circuit diagram and component layout. Pay attention to component orientation (e.g., diodes, electrolytic capacitors, ICs). Video 1 (1:34-2:04) demonstrates the soldering process for resistors.

5.3 Enclosure Assembly

Once all components are soldered and verified, assemble the acrylic panels around the main board using the nylon posts and locking screws.

6. Operating Instructions

Familiarize yourself with the connectors, switches, and keys on the DSO183 board for proper operation.

Figure 9: Labeled diagram of the DSO183 board showing power input, signal input, coupling switch, sensitivity switches, and control keys.

6.1 Basic Operation Methods

• [SEL] button: Select the parameter to be adjusted. The selected parameter will be highlighted on the display.
• [+] and [-] buttons: Adjust the selected parameter's value.
• [OK] button: Frames the waveform (enters pause acquisition state). Press again to resume acquisition.
• [CPL] switch: Select DC, AC, or GND coupling. When the coupling switch is placed in the GND position, the input signal is disconnected, and the oscilloscope input is grounded (i.e., 0V input).
• [SEN1]/[SEN2]: Adjust the sensitivity. The product of [SEN1] and [SEN2] is the actual sensitivity, displayed in the lower left corner of the screen.

6.2 Signal Generator Output

The DSO183 includes a built-in signal generator capable of outputting sine, triangle, and square waves. Use the dedicated buttons (SINE, TRI, SQR) to select the desired waveform. The 1KHz and 3.3V outputs are also available for testing.

7. Maintenance

• Keep the device clean and free from dust. Use a soft, dry cloth for cleaning.
• Avoid exposing the oscilloscope to extreme temperatures, humidity, or direct sunlight.
• Handle with care to prevent physical damage to the PCB or components.
• Ensure proper power supply (DC 5V via USB Type C) to prevent damage.

8. Troubleshooting

• No power/display: Check USB power connection. Ensure all soldered joints are secure and there are no short circuits.
• Incorrect waveform display: Verify probe connections and settings (coupling mode, sensitivity). Ensure the signal source is functioning correctly.
• Component not working after assembly: Double-check soldering for cold joints or bridges. Verify component values and orientation.
• Language issue: Check the JP4 jumper setting on the back of the board. Short for Chinese, open for English.

9. User Tips

• Verify Components: Before soldering, always use a multimeter to check the values of resistors and other components. This helps prevent errors and ensures correct functionality.
• Clean Soldering: Ensure all solder joints are clean and shiny. Cold or bridged joints can lead to malfunctions.
• Start Simple: If you are new to oscilloscopes, begin by testing simple, known waveforms from the built-in signal generator before connecting external signals.
• Refer to Diagrams: Keep the circuit diagram and component layout handy during assembly and troubleshooting.
