4.2 Почетно повезивање

To begin using the U-18 USB Tester Meter, connect it inline between your power source (charger, power bank) and the device you wish to test.

1. Connect the USB-A Input (4V-24V) or Type-C Input port of the U-18 to your power source.
2. Connect the USB-A Out (0-6.5A) or Type-C Output port of the U-18 to your device (e.g., smartphone, tablet, laptop).
3. The display will automatically power on and begin showing real-time measurement data.

5. Упутство за употребу

5.1 Basic Measurement Display

Upon connection, the tester will display key parameters on its 1.77-inch TFT screen.

Figure 5.1: The tester's display showing voltage, current, power, energy, capacity, and fast charging protocol information.

• Волtagе Дисплеј: Приказује волtagе (В).
• Тренутни приказ: Shows the real-time current (A).
• Екран напајања: Shows the real-time power (W).
• Енергетска статистика: Accumulates total energy consumed (Wh).
• Capacity Statistics: Accumulates total charge capacity (Ah).
• Fast Charging Protocol Display: Indicates detected fast charging protocols (e.g., PD, QC2.0, QC3.0).

5.2 Navigating Display Interfaces

The U-18 offers 7 types of display interfaces. Use the KEY - и КЕИ + buttons (labeled 2 and 3 in Figure 3.2) to cycle through different display modes and settings.

5.3 Cable Internal Resistance Measurement

This feature allows you to assess the quality of your USB cables.

Figure 5.3: The tester connected to a power source and device, displaying cable resistance measurement.

1. Connect the U-18 to a power source.
2. Navigate to the "Cable Measurement" interface (refer to Figure 5.2).
3. Connect the cable you wish to test between the U-18's output and a load (e.g., a device drawing current).
4. The system will automatically calculate and display the cable's internal resistance. A lower resistance indicates a better quality cable.

5.4 Display Orientation

To toggle the display orientation, long-press the КЕИ + button (labeled 3 in Figure 3.2).

6. Одржавање

• Keep the device clean and dry. Use a soft, dry cloth to wipe the screen and casing.
• Избегавајте употребу абразивних средстава за чишћење или растварача.
• Чувајте уређај на хладном и сувом месту када се не користи.

КСНУМКС. Решавање проблема

• Без приказа: Ensure the tester is properly connected to a power source and a load. Check if the power source is active.
• Нетачна очитавања: Verify that all connections are secure. Ensure the power source and load are functioning correctly. Readings can be affected by poor quality cables or unstable power sources.
• Уређај се не пуни: Check the connections between the tester, power source, and device. Ensure the power source is providing sufficient power.
• Cable Resistance Reads 9999.9Ω: This typically indicates an open circuit or a very poor connection in the cable being tested. Re-check cable connections.
