4. Thiết lập

4.1 Lắp đặt pin

The AIOMEST AI-7200D requires two 1.5V AAA batteries (included). To install or replace batteries, locate the battery compartment on the back of the device, open it, insert the batteries according to polarity markings, and close the compartment securely.

4.2 Kết nối dây dẫn thử nghiệm

Đối với hầu hết các phép đo (thể tíchtage, resistance, capacitance, diode, continuity, temperature), connect the black test lead to the 'COM' terminal and the red test lead to the 'VΩmA' terminal. Ensure connections are firm.

5. Chế độ hoạt động và phép đo

5.1 Hoạt động chung

Turn the rotary dial to the desired function. The meter typically defaults to AUTO mode, automatically selecting the appropriate range for measurement. Press the 'SEL' button to cycle through sub-functions within a mode (e.g., AC/DC voltage, diode/tính liên tục).

Figure 5.1: The Auto Range feature simplifies operation by automatically detecting the measurement type and range.

5.2 Đo dòng điện AC/DC (Cl)amp)

To measure AC or DC current, rotate the dial to the 'A~' or 'A=' position. Press the clamp trigger to open the jaws and enclose a single conductor (not a bundle of wires). The current reading will appear on the display. For DC current, ensure the conductor is placed in the correct orientation if polarity is critical.

5.3 Âm lượng AC/DCtage Đo lường

Connect the test leads as described in Section 4.2. Rotate the dial to 'V~' for AC voltage hoặc 'V=' cho điện áp DCtage. Touch the probes to the points where voltage needs to be measured. The reading will be displayed.

5.4 Resistance, Capacitance, Diode, Continuity, NCV, Temperature

Rotate the dial to the corresponding symbol for Resistance (Ω), Capacitance (∔), Diode (→|), Continuity (•))), or Temperature (°C/°F). For NCV, select the NCV mode and bring the clamp head near the AC voltage source. The meter will beep and light up to indicate voltage hiện diện.

5.5 Chức năng giữ dữ liệu

Nhấn nút 'HOLD' để giữ nguyên giá trị hiện tại trên màn hình. Nhấn lại nút đó để bỏ chức năng giữ.

6. Bảo trì

6.1 Thay thế pin

When the low battery indicator appears on the display, replace the two 1.5V AAA batteries promptly to ensure accurate measurements and proper device function.

6.2 Vệ sinh

Wipe the device with a dry, soft cloth. Do not use abrasive cleaners or solvents. Ensure the device is powered off and disconnected from any electrical source before cleaning.

KHAI THÁC. Xử lý sự cố

• Màn hình "OL": Indicates an over-range condition. The measured value exceeds the current range selected. Switch to a higher range or ensure the measurement is within the device's capabilities.
• Không hiển thị/Màn hình mờ: Kiểm tra việc lắp đặt và sạc pin. Thay pin nếu cần thiết.
• Đọc không chính xác: Ensure test leads are properly connected and not damaged. Verify the correct measurement mode and range are selected.
• Tự động tắt nguồn: The meter will automatically power off after 15 minutes of inactivity to conserve battery life. Press any button or rotate the dial to turn it back on.
