3. Настройка и основные операции

3.1 Подключение тестера

1. Identify the appropriate input port (USB-A or Type-C) on the tester based on your power source.
2. Connect the power source (e.g., wall charger, power bank) to the tester's input port.
3. Connect the device you wish to test (e.g., smartphone, tablet) to the tester's corresponding output port (USB-A or Type-C).
4. The tester's screen should illuminate and begin displaying real-time data.

3.2 Reading Basic Measurements

Рисунок 2: Example of the tester's display showing various measurement data, including voltage, current, power, energy statistics, capacity statistics, and fast charging protocol information.

Upon connection, the main display will show key parameters:

• Томtagе (В): The electrical potential difference.
• Ток (А): The flow rate of electric charge.
• Мощность (Вт): The rate at which electrical energy is transferred.
• Емкость (Ач): Accumulated charge over time.
• Энергия (Вт·ч): Accumulated energy over time.
• Д+/Д- Томtage: Data line voltages, useful for protocol detection.
• Протокол: Indicates detected fast charging protocols (e.g., QC2.0, QC3.0, PD).

Используйте ВХОДИТЬ, KEY -, КЛЮЧ +, и НАЗАД keys to navigate through different display interfaces and settings menus. A long press on the КЛЮЧ + button can rotate the display orientation.

• Настройки системы: Adjust display brightness, standby time, language, and perform a factory reset.
• Простой режим интерфейса: Provides a streamlined view важных данных.
• Ripple/Voltage/Current Curve Interface: Displays real-time graphs of voltagе и колебания тока.

4.2 Измерение внутреннего сопротивления кабеля

Рисунок 4: The tester performing a wire internal resistance measurement, displaying reference voltage/current, real voltage/current, difference, and calculated cable resistance.

To measure cable internal resistance:

1. Navigate to the 'Cable Measurement' interface using the navigation keys.
2. Connect the power source directly to the tester's input, and then connect the cable to be tested to the tester's output.
3. The tester will employ the voltage drop method to measure the resistance, automatically calculating and displaying the cable resistance value. A lower resistance indicates a more efficient cable.

4.3 Fast Charging Protocol Detection and Trigger

The tester can automatically detect and trigger various fast charging protocols. Navigate to the 'Protocol Detection/Trigger' interface to:

• Автоматическое обнаружение: The tester will attempt to identify the fast charging protocol supported by the connected power source.
• Ручной триггер: You can manually select and trigger specific protocols like PD, QC2.0, or QC3.0 to test compatibility and performance.

6. Поиск Неисправностей

6.1 Display Not Lighting Up with Type-C PD

Рисунок 6: Visual guide for troubleshooting when the tester screen does not light up with a Type-C PD connection, showing solutions like flipping the connector or using the built-in Type-C interface.

If the tester screen does not light up when connected to a Type-C PD power source:

1. Flip the Type-C connector: Type-C connectors are reversible. Try unplugging and re-inserting the connector with the opposite orientation.
2. Use the built-in Type-C interface: Ensure you are using the dedicated Type-C input/output ports on the tester for PD connections.

Примечание: When the PD power supply is not connected to a fast charging device, it may not be powered by default.

6.2 Неточные показания

• Убедитесь, что все соединения надежны и свободны от мусора.
• Test with a different cable or power source to rule out external factors.
• Perform a factory reset via the system settings menu if persistent issues occur.

7. Информация по технике безопасности
