- Stabilizace: After installing a battery, allow a few seconds for the voltage and internal resistance readings on the display to stabilize before proceeding with tests.
5. Návod k obsluze
The tester allows for independent operation of its four channels.

Obrázek 4: Display and control buttons. This image provides a detailed view of the tester's screen and the four control buttons located below it, used for navigation and operation.
5.1. Basic Navigation and Channel Selection
- Použijte Channel /CHN Key (16) to switch between the four independent channels (CHN 1 to CHN 4).
- The Menu /M Key (13) is used to enter or exit menu settings.
- The Adjust /S Key (14) is used to change values or select options within a menu.
- The Start/Stop /R/S Button (15) initiates or terminates a test cycle.
5.2. Automatic Charge and Discharge Cycles
The tester supports fully automatic charging and discharging cycles (1-9 cycles adjustable in auto mode).
- Vyberte požadovaný kanál pomocí Channel /CHN Key.
- Stiskněte tlačítko Menu /M Key pro vstup do výběru režimu.
- Použijte Adjust /S Key to select 'AUTO' mode.
- Adjust the number of cycles (LOOP: 1-9) using the Adjust /S Key v případě potřeby.
- Stiskněte tlačítko Start/Stop /R/S Button to begin the automatic cycle. The charging process automatically stops when the battery is full.
5.3. Internal Resistance Measurement
The device utilizes the DC two-wire method to provide reference internal resistance values.
- For the most accurate reading, measure internal resistance when the battery is fully charged.
- The internal resistance value is displayed as 'mR' on the screen (5).
5.4. Setting Stop Discharge Voltage
You can choose from 11 stop-discharge voltage levels (2.5V to 3.5V).
- Vyberte požadovaný kanál.
- Enter the menu using the Menu /M Key.
- Navigate to the 'STOP' voltage nastavení.
- Použijte Adjust /S Key to select the desired stop discharge voltage (2.5V, 2.6V, ..., 3.5V).
- Potvrďte nastavení a opusťte nabídku.
5.5. Důležité poznámky k použití
- Discharge current is fixed at a maximum of approximately 1A (non-adjustable, non-constant current).
- Nabíjecí voltage is fixed at 4.2V.
- This tester is není kompatibilní with LiFePO4 batteries.
6. Bezpečnostní informace
The device incorporates several safety features to ensure safe operation:
- Ochrana proti přehřátí: The integrated radiator fan (11) and internal sensors help prevent the device from overheating during operation.
- Automatické vypnutí: Settings are automatically saved in case of power loss.
- Charge Cutoff: Automatic charge cutoff prevents overcharging of batteries.
- Zastávka vypouštění: Configurable stop discharge voltage prevents over-discharging.
Always ensure correct battery polarity when inserting batteries to prevent damage to the device or batteries.
7. Údržba
- Udržujte zařízení čisté a bez prachu. K čištění používejte měkký, suchý hadřík.
- Avoid exposing the tester to moisture or extreme temperatures.
- Ensure the cooling fan (11) is not obstructed to maintain proper airflow.
- Pokud zařízení nepoužíváte, skladujte jej na suchém a chladném místě.
8. Řešení problémů
- Internal Resistance Readings Appear High at Low Voltages: If internal resistance readings seem unusually high, reinstall the battery. This can often provide a more accurate measurement.
- Zařízení se nezapíná: Ensure the Type-C power cable is securely connected to a functional 5V DC power source. Try a different cable or adapter if necessary.
- Battery Not Detected: Verify that the battery is correctly inserted with the correct polarity and that it is a compatible 18650 flat-top lithium battery.
