4. Configuració

1. Connexió d'alimentació: Connect the tester to a 5V DC power source using one of the two Type-C interfaces. An adapter and cable are typically included.
2. Inserció de la bateria: Insert flat-top 18650 batteries into the designated battery holders (3, 4, 5, 6). Ensure correct polarity (+ and -). The tester supports flat-top 18650 batteries.
3. Estabilització: 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. Instruccions de funcionament

The tester allows for independent operation of its four channels.

Figura 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

• Utilitza el Channel /CHN Key (16) to switch between the four independent channels (CHN 1 to CHN 4).
• El Menu /M Key (13) is used to enter or exit menu settings.
• El Adjust /S Key (14) is used to change values or select options within a menu.
• El 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).

1. Select the desired channel using the Channel /CHN Key.
2. Premeu el botó Menu /M Key per entrar a la selecció del mode.
3. Utilitza el Adjust /S Key to select 'AUTO' mode.
4. Adjust the number of cycles (LOOP: 1-9) using the Adjust /S Key si cal.
5. Premeu el botó 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).

1. Seleccioneu el canal desitjat.
2. Enter the menu using the Menu /M Key.
3. Navigate to the 'STOP' voltagConfiguració.
4. Utilitza el Adjust /S Key to select the desired stop discharge voltage (2.5V, 2.6V, ..., 3.5V).
5. Confirmeu la configuració i sortiu del menú.

5.5. Notes d'ús importants

• Discharge current is fixed at a maximum of approximately 1A (non-adjustable, non-constant current).
• Vol. De càrregatage està fixat a 4.2 V.
• This tester is no compatible with LiFePO4 batteries.

6. Informació de seguretat

The device incorporates several safety features to ensure safe operation:

• Protecció contra el sobreescalfament: The integrated radiator fan (11) and internal sensors help prevent the device from overheating during operation.
• Apagat automàtic: Settings are automatically saved in case of power loss.
• Charge Cutoff: Automatic charge cutoff prevents overcharging of batteries.
• Parada de descàrrega: Configurable stop discharge voltage prevents over-discharging.

Always ensure correct battery polarity when inserting batteries to prevent damage to the device or batteries.

7. Manteniment

• Mantingueu el dispositiu net i lliure de pols. Feu servir un drap suau i sec per netejar-lo.
• Avoid exposing the tester to moisture or extreme temperatures.
• Ensure the cooling fan (11) is not obstructed to maintain proper airflow.
• Guardeu el dispositiu en un lloc sec i fresc quan no l'utilitzeu.

8. Solució De Problemes

• 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.
• El dispositiu no s'encén: Ensure the Type-C power cable is securely connected to a functional 5V DC power source. Try a different cable or adapter if necessary.
• Bateria no detectada: Verify that the battery is correctly inserted with the correct polarity and that it is a compatible 18650 flat-top lithium battery.
