1. නිෂ්පාදන අවසන්view
The DSO138 is engineered as a training oscilloscope kit, emphasizing fundamental oscilloscope functions for straightforward assembly and operation. It incorporates a Cortex-M3 ARM processor (STM32F103C8) and a 2.4-inch TFT LCD, providing clear waveform visualization. This specific 13803K kit features pre-soldered Surface Mount Device (SMD) components and a pre-programmed Microcontroller Unit (MCU), which simplifies the initial assembly process.
2. සැකසීම සහ එකලස් කිරීම
While the SMD components are pre-soldered and the MCU is pre-programmed, the assembly of through-hole components and general soldering are still required for other parts of the kit. Please refer to the detailed assembly instructions and schematics provided with your physical kit for precise, step-by-step guidance.
බල සැපයුම් අවශ්යතාවය: A 9V DC power supply is essential for the operation of the DSO138 and is not included with this kit. Ensure that the power supply you use is compatible with the device's specifications.

4. නඩත්තු කිරීම
To ensure the longevity and optimal performance of your DSO138 oscilloscope, follow these maintenance guidelines:
- පිරිසිදු කිරීම: උපාංගය පිරිසිදුව හා දූවිලි වලින් තොරව තබා ගන්න. පිරිසිදු කිරීම සඳහා මෘදු වියළි රෙද්දක් භාවිතා කරන්න. උල්ෙල්ඛ පිරිසිදු කරන්නන් හෝ ද්රාවක භාවිතා කිරීමෙන් වළකින්න.
- පාරිසරික තත්ත්වයන්: Do not expose the oscilloscope to extreme temperatures, high humidity, or direct sunlight. Store it in a dry, stable environment.
- හැසිරවීම: භෞතික හානි වළක්වා ගැනීම සඳහා උපාංගය ප්රවේශමෙන් හසුරුවන්න. බිම හෙළීමෙන් හෝ දැඩි බලපෑම්වලට ලක්වීමෙන් වළකින්න.
- වෙනස් කිරීම්: Do not attempt to modify the internal circuitry beyond the intended assembly steps. Unauthorized modifications can void any potential warranty and may damage the device.
5. දෝශ නිරාකරණය
This section addresses common issues you might encounter with your DSO138 kit.
පොදු ගැටළු:
- සංදර්ශකය හෝ බලය නැත: Ensure the 9V DC power supply is correctly connected and functioning. If the kit was recently assembled, double-check all power-related connections and soldering points for continuity and shorts.
- Distorted or Unstable Waveforms: Verify that the probe is securely connected and that its 1X/10X switch (if present) is set appropriately for your measurement. Adjust the vertical sensitivity (V/Div) and timebase (s/Div) settings on the oscilloscope to properly scale the waveform.
- Component Overheating: If any component, such as a diode (e.g., D2), becomes excessively hot during operation, immediately disconnect power. This often indicates a short circuit, an incorrectly installed component, or a faulty part. Consult the provided schematic for correct component placement and values.
For more detailed troubleshooting steps, refer to the comprehensive troubleshooting guide and schematic included with your kit. If issues persist, contact JYETech customer support for further assistance.
