3. Інструкція з експлуатації
The Hantek DSO4084B offers intuitive controls for various measurement tasks.
3.1. Basic Waveform Adjustment
- Регулювання Voltage: Use the vertical scale knobs (labeled "Vertical") for each channel to adjust the voltage per division (V/div). The button next to the knob allows for fine-tuning the voltage.
- Adjusting Waveform Position: Use the position knobs for each channel to move the waveform vertically on the screen.
- Enabling Multiple Channels: All four channels can be activated simultaneously. Use the dedicated buttons for each channel (CH1, CH2, CH3, CH4) to toggle them on or off. Adjust voltage and position for each active channel independently.
- Автоматичне налаштування: Натисніть АВТО button to automatically adjust the oscilloscope settings for a stable waveform display. For example, when measuring a DC 5V signal, the auto function might set the display to 2V per division.
3.2. Функції вимірювання
The oscilloscope provides extensive measurement capabilities:
- Автоматичні вимірювання: Access over 32 types of automatic measurements by pressing the ВИМІР button. This displays parameters like Vpp (peak-to-peak voltage), Vmax, Vmin, frequency, period, and more. Pressing ВИМІР again will hide the measurement results.
- Тригерна система: Utilize the advanced digital trigger system with over 14 types of trigger functions (edge, overtime, pulse, pattern, interval, etc.) to capture specific events.
- Декодування послідовної шини: For serial bus protocols, the device can quickly and intuitively display bus protocol information in table form.
3.3. Coupling Settings (DC/AC)
To accurately measure different signal types, adjust the coupling setting:
- DC Coupling: Select DC coupling (usually via a menu accessed by a function button like F1) to measure both AC and DC components of a signal.
- З'єднання змінного струму: Select AC coupling to block the DC component and only display the AC component of a signal. This is useful for observing small AC signals superimposed on a large DC offset.
- Обмеження пропускної здатності: The oscilloscope features a 20MHz bandwidth limit option (e.g., BW 20M). Activating this can help remove high-frequency noise or unwanted signals above 20MHz, providing a cleaner waveform for analysis.
- Adjusting Time Base: Use the horizontal scale knob (labeled "Horizontal") to adjust the time per division (s/div) to view більшу або меншу частину форми хвилі по горизонталі.

4. Технічне обслуговування
Proper maintenance ensures the longevity and accuracy of your Hantek DSO4084B oscilloscope:
- Прибирання: Regularly clean the exterior of the oscilloscope with a soft, dry cloth. For stubborn dirt, use a slightly damp cloth with mild detergent. Avoid abrasive cleaners or solvents.
- Догляд за екраном: Use a soft, lint-free cloth specifically designed for electronics screens to clean the display. Do not press hard or use harsh chemicals.
- Вентиляція: Переконайтеся, що вентиляційні отвори чисті від пилу та перешкод, щоб запобігти перегріву.
- Зберігання: When not in use, store the oscilloscope in a clean, dry environment away from direct sunlight, extreme temperatures, and excessive humidity.
- Догляд за зондом: Handle probes carefully. Avoid bending or stressing the cables. Store them properly to prevent damage to the tips and connectors.
- Калібрування: For critical measurements, periodic calibration by a qualified service center is recommended to maintain accuracy.
5. Вирішення проблем
У цьому розділі наведено рішення поширених проблем, з якими ви можете зіткнутися:
| проблема | Можлива причина | Рішення |
|---|---|---|
| Немає живлення | Power cable not connected, power outlet faulty, power switch off. | Check power cable connection, try a different outlet, ensure power switch is on. |
| Не відображається хвиля | Input signal absent, probe not connected, channel off, incorrect vertical/horizontal settings. | Verify signal source, check probe connection, activate channel, use AUTO button or manually adjust V/div and s/div. |
| Нестабільна форма хвилі | Incorrect trigger settings, noisy signal. | Adjust trigger level and mode. Consider using the 20MHz bandwidth limit to reduce noise. |
| Невірні вимірювання | Improper probe attenuation setting, uncalibrated device. | Ensure probe attenuation (e.g., 1X, 10X) matches the oscilloscope setting. Consider professional calibration. |
