3. محتویات بسته
مطمئن شوید که تمام موارد ذکر شده در زیر در بسته شما موجود است:
- 1 x YWBL-WH VI Curve Tester Unit
- 2 x BNC Cables
- 2 x Test Cables (Red and Black)
4. راه اندازی
Follow these steps to set up your VI Curve Tester:
- Connect to Oscilloscope: Connect the two BNC cables from the output ports on the top of the VI Curve Tester to the input channels (e.g., Channel 1 and Channel 2) of your oscilloscope.
- Connect Test Cables: Insert the red test cable into the red 'A' terminal and the black test cable into the black 'COM' terminal on the front panel of the VI Curve Tester. If using the second channel, insert the blue test cable into the blue 'B' terminal.
- Power On Oscilloscope: Ensure your oscilloscope is powered on and configured to display the input channels. The VI Curve Tester is a passive device and does not require external power.

5. دستورالعمل های عملیاتی
This section details how to operate the VI Curve Tester for circuit analysis.
- Prepare the Circuit Board: Ensure the circuit board to be tested is completely powered off and any large capacitors are discharged.
- Select Test Frequency: Use the frequency selection buttons (LOW, MED1, MED2, HIGH) on the front panel to choose the desired test frequency. The selected frequency will be indicated by an illuminated LED. Different frequencies can reveal different characteristics of components.
- اتصال به مدار: Connect the red and black test probes to the points on the circuit board you wish to test. For comparative analysis, connect the blue probe to another point or a known good component.
- Observe VI Curve: Observe the VI curve displayed on your oscilloscope. The shape of the curve provides information about the component's characteristics (e.g., resistor, capacitor, diode, short circuit, open circuit).
- Single Channel / Alternate Display: Use the 'A/B' button to switch between displaying a single channel's curve or alternating between two channels for comparison. This is useful for comparing a faulty component's curve with a known good one.
- تنظیم تنظیمات اسیلوسکوپ: Adjust the oscilloscope's horizontal and vertical sensitivity (Volts/Div and Time/Div) to obtain a clear and stable VI curve display.

6. تعمیر و نگهداری
Proper maintenance ensures the longevity and accuracy of your VI Curve Tester.
- تمیز کردن: دستگاه را با یک پارچه نرم و خشک پاک کنید. از پاک کننده ها یا حلال های ساینده استفاده نکنید.
- ذخیره سازی: دستگاه را در جای خشک و خنک و دور از نور مستقیم خورشید و دمای شدید نگهداری کنید.
- مراقبت از کابل: Inspect BNC and test cables regularly for damage. Replace any frayed or broken cables immediately. Avoid sharp bends or kinks in the cables.
7 عیب یابی
If you encounter issues with your VI Curve Tester, refer to the following common problems and solutions:
| مشکل | علت احتمالی | راه حل |
|---|---|---|
| No VI curve displayed on oscilloscope. | Incorrect oscilloscope settings, loose cable connections, or no signal from the tester. | Check BNC cable connections. Ensure oscilloscope channels are enabled and set to appropriate input mode (e.g., XY mode for VI curves). Adjust oscilloscope's vertical and horizontal sensitivity. |
| Distorted or unstable VI curve. | Interference, faulty test cables, or improper connection to the circuit. | Ensure test probes are making good contact. Check for external interference. Try different test cables. Verify the circuit board is fully discharged. |
| Frequency selection buttons not responding. | نقص داخلی. | برای کمک با پشتیبانی مشتری تماس بگیرید. |
