7. Test ② Type-C external discharge interface: An alternative interface for testing batteries that do not fit the 18650 holder.
8. Test ① charging and discharging 18650 battery compartment: The primary slot for testing 18650 batteries.
9. 1.77 inch display screen: Shows real-time test data and settings.
10. 10W8ΩJ discharge cement resistance ×2: Resistors used for discharging batteries during tests.

Ważna uwaga: Despite some product descriptions, user feedback indicates this device functions as a single-channel tester. The left battery slot (1) is primarily for powering the device, and the right slot (8) is the main test channel. The Type-C external discharge interface (7) can also be used for testing, but not simultaneously with slot (8).

4. Konfiguracja

4.1 Zasilanie urządzenia

The tester can be powered in two ways:

• Via Type-C: Connect a 5V Type-C power adapter and cable (included) to the Type-C 5V power supply interface (3).
• Via Power Supply Battery: Insert an 18650 battery into the Power supply battery compartment (1) on the left side of the device. This battery will power the tester's internal circuitry.

4.2 Battery Installation for Testing

To test an 18650 battery:

• Insert the flat-top 18650 battery into the Test ① charging and discharging 18650 battery compartment (8) on the right side of the device, ensuring correct polarity.
• Alternatively, for batteries that do not fit the 18650 holder, connect them to the Test ② Type-C external discharge interface (7) using appropriate cables.

5. Instrukcja obsługi

5.1 Włączanie/wyłączanie zasilania

• Naciśnij ON/OFF/Menu button (4) to power on the device.
• Naciśnij i przytrzymaj ON/OFF/Menu button (4) to power off the device.

5.2 Selecting Test Mode

Naciśnij Regulować button (5) to cycle through the available test modes:

• Tryb automatyczny: Performs a full charge, then discharges to measure capacity, and finally recharges the battery. This cycle can be adjusted from 1 to 9 loops.
• Tryb ŁADOWANIA: Charges the battery to 4.2V.
• Tryb rozładowania: Discharges the battery to the selected stop-discharge voltage.

5.3 Setting Stop-Discharge Voltage

In DISCHARGE or AUTO mode, you can select from 11 stop-discharge voltage levels ranging from 2.5V to 3.5V. Use the Regulować button (5) to change this setting before starting the test.

5.4 Starting and Stopping a Test

• Naciśnij Uruchom/Zatrzymaj button (6) to begin the selected test mode.
• Naciśnij Uruchom/Zatrzymaj button (6) again to pause or stop an ongoing test.
• When a test is stopped, a long press of the Uruchom/Zatrzymaj button (6) will reset the onscreen data.

5.5 Internal Resistance Measurement

The device utilizes the DC two-wire method to provide a reference internal resistance value. For the most accurate reading, measure the internal resistance when the battery is fully charged.

6. Konserwacja

• Utrzymuj urządzenie w czystości, bez kurzu i zanieczyszczeń. Do czyszczenia używaj miękkiej, suchej ściereczki.
• Ensure proper ventilation during operation, especially during discharge cycles, as the device can generate heat. Do not obstruct the discharge resistors.
• Przechowuj tester w suchym miejscu, z dala od bezpośredniego światła słonecznego i ekstremalnych temperatur.

7. Rozwiązywanie Problemów

• Urządzenie się nie włącza: Verify that the Type-C power adapter is correctly connected and supplying 5V, or ensure the power supply battery in slot (1) is charged and properly inserted.
• Test does not start: Check that the battery is correctly inserted into the test compartment (8) with the correct polarity. Ensure a test mode (AUTO, CHARGE, DISCHARGE) has been selected.
• Inaccurate internal resistance readings: Reinstall the battery and ensure it is fully charged for the most accurate internal resistance measurement. Readings can be higher at low battery voltagt.j.
• Urządzenie wydaje się gorące: This is normal during discharge cycles due to the resistive load. The device has built-in overheating protection. Ensure good airflow around the device.
