3. Налаштування

Follow these steps to set up your battery capacity tester for first use:

1. Підключення живлення: Connect the device to a 5V DC power source using a Type-C cable (not included) via the Type-C 5V Power Supply Interface (3).
2. Optional Power Supply Battery: For portable use or to power the device itself, insert a compatible battery into the Power Supply Battery Compartment (1). Note that this battery is for device power only and not for testing.
3. Battery Insertion for Test:
   • For 18650 batteries, insert the battery into the Test ① Charging and Discharging 18650 Battery Compartment (8), ensuring correct polarity.
   • For external batteries or devices, connect them to the Test ② Type-C External Discharge Interface (7).
4. Увімкнення: Press the "ON/OFF/Menu" button (4) to power on the device. The display screen (9) will illuminate.
5. Стабілізація: After installing a battery, wait a few seconds for the voltage and internal resistance readings to stabilize on the display before proceeding with tests.

4. Інструкція з експлуатації

The tester offers various modes for battery analysis. Use the "ON/OFF/Menu" (4), "Adjust" (5), and "Start/Stop" (6) buttons to navigate and control operations.

4.1. Вибір режиму

Press the "Adjust" button (5) to cycle through the available modes:

• Автоматичний режим: Performs a full charge-discharge cycle (or multiple cycles) to measure capacity.
• CHARGE Mode: Charges the battery to 4.2V.
• DISCHARGE Mode: Discharges the battery to a user-selected stop voltage.

4.2. Starting and Stopping Tests

Once a mode is selected and settings are configured (if applicable), press the "Start/Stop" button (6) to begin the test. Press it again to stop the test at any time.

When a test is stopped, a long press of the "Start/Stop" button (6) will reset the on-screen data.

4.3. AUTO Mode Operation

1. Insert the battery into the Test ① compartment (8) or connect to Test ② (7).
2. Press "Adjust" (5) until "MODE:AUTO" is displayed.
3. Use the "ON/OFF/Menu" button (4) to adjust the number of cycles (1-9) and the stop-discharge voltage (від 2.5 до 3.5 В).
4. Press "Start/Stop" (6) to begin. The tester will automatically charge, discharge, and recharge the battery for the set number of cycles, displaying cumulative capacity and energy.
5. The test will automatically stop when all cycles are completed.

4.4. CHARGE Mode Operation

1. Insert the battery into the Test ① compartment (8) or connect to Test ② (7).
2. Press "Adjust" (5) until "MODE:CHG" is displayed.
3. Press "Start/Stop" (6) to begin charging. The charging voltage is fixed at 4.2V.
4. Charging automatically stops when the battery is full.

3. Use the "ON/OFF/Menu" button (4) to select the desired stop-discharge voltage (від 2.5 до 3.5 В).
4. Press "Start/Stop" (6) to begin discharging. The discharge current is fixed at approximately 1A.
5. Discharging automatically stops when the battery reaches the set stop voltage.

4.6. Internal Resistance Measurement

The tester provides a reference internal resistance value (mR) using the DC two-wire method. For the most accurate reading, measure when the battery is fully charged. The internal resistance is displayed on the screen (10).

5. Технічне обслуговування

• Прибирання: Тримайте пристрій чистим та без пилу та сміття. Використовуйте м’яку суху тканину для очищення.

• Обробка: Поводьтеся з пристроєм обережно, щоб уникнути фізичних пошкоджень.
• Управління теплом: The discharge load resistors (10) can get hot during operation. Ensure adequate ventilation and avoid touching them during or immediately after a test. The device includes active cooling and high-temperature protection.

6. Вирішення проблем

• Inaccurate Internal Resistance Readings: If internal resistance readings appear high, especially at low battery voltages, try reinstalling the battery or measuring when the battery is fully charged for a more accurate result.
• Пристрій не вмикається: Ensure the Type-C power cable is securely connected to a 5V DC power source, or that a charged battery is inserted into the Power Supply Battery Compartment (1).
• Test Not Starting: Verify that a battery is properly inserted with correct polarity and that a test mode has been selected. Press the "Start/Stop" button (6) firmly.
• Немає дисплея: Check power connection. If the device is powered but the screen is blank, try pressing the "ON/OFF/Menu" button (4).
• Проблеми сумісності: This tester is not compatible with LiFePO4 batteries. Ensure you are testing compatible lithium-ion batteries (e.g., 18650 flat-top).
• Confusing Channel Operation: Remember that Test ① (18650 compartment) and Test ② (external Type-C) cannot be used simultaneously for testing.
