3. இயக்க வழிமுறைகள்
The Hantek DSO4084B offers intuitive controls for various measurement tasks.
3.1. Basic Waveform Adjustment
- சரிசெய்தல் தொகுதிtage: 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.
- தானியங்கு அமைவு: அழுத்தவும் ஆட்டோ 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. அளவீட்டு செயல்பாடுகள்
The oscilloscope provides extensive measurement capabilities:
- தானியங்கி அளவீடுகள்: Access over 32 types of automatic measurements by pressing the MEAS button. This displays parameters like Vpp (peak-to-peak voltage), Vmax, Vmin, frequency, period, and more. Pressing MEAS again will hide the measurement results.
- தூண்டுதல் அமைப்பு: Utilize the advanced digital trigger system with over 14 types of trigger functions (edge, overtime, pulse, pattern, interval, etc.) to capture specific events.
- Serial Bus Decoding: 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.
- ஏசி இணைப்பு: 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.
- அலைவரிசை வரம்பு: 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 more or less of the waveform horizontally.

4. பராமரிப்பு
Proper maintenance ensures the longevity and accuracy of your Hantek DSO4084B oscilloscope:
- சுத்தம்: 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.
- திரை பராமரிப்பு: Use a soft, lint-free cloth specifically designed for electronics screens to clean the display. Do not press hard or use harsh chemicals.
- காற்றோட்டம்: அதிக வெப்பமடைவதைத் தடுக்க காற்றோட்டத் திறப்புகள் தூசி மற்றும் தடைகள் இல்லாமல் இருப்பதை உறுதி செய்யவும்.
- சேமிப்பு: When not in use, store the oscilloscope in a clean, dry environment away from direct sunlight, extreme temperatures, and excessive humidity.
- ஆய்வு பராமரிப்பு: Handle probes carefully. Avoid bending or stressing the cables. Store them properly to prevent damage to the tips and connectors.
- அளவுத்திருத்தம்: For critical measurements, periodic calibration by a qualified service center is recommended to maintain accuracy.
