5. Podešavanje

1. Connect the power adapter to the charger's DC input port.
2. Plug the power adapter into a suitable wall outlet. The LCD screen will illuminate, indicating the charger is ready.
3. Observe the 'Manual & Auto' switch on the side of the charger. For most users, the 'Auto' mode is recommended for automatic current selection. For advanced users, switch to 'Manual' mode to set charging parameters.

This image highlights the 'Manual & Auto' switch located on the side of the charger. This switch allows users to toggle between automatic current selection and manual control over charging parameters.

6. Uputstvo za upotrebu

Umetanje baterija:

Carefully insert one or more rechargeable batteries into the charging bays, ensuring correct polarity (+/-). The charger will automatically detect the battery type and display information on the LCD.

Automatski način rada:

In 'Auto' mode, the charger intelligently selects the optimal charge current based on the battery's internal resistance and type. This is the default and recommended mode for general use.

This image demonstrates the charger's intelligent function to automatically select the optimal charge current. The LCD screen shows the charger assessing the battery's internal resistance to determine the most suitable charging rate.

Manual Mode (Setting Charge Current):

If the 'Manual & Auto' switch is set to 'Manual', you can adjust the charge current:

1. After inserting a battery, press the MODE button to select the desired function (Charge, Discharge, Cap Test, Repair).
2. Pritisnite CURRENT button to cycle through available charge current options: 250mA, 500mA (default), 1000mA, 1500mA, 2000mA, 2500mA, 3000mA.
3. The selected current will be applied to the battery in that slot. Each slot can have different settings.

This image displays the manual mode interface on the LCD screen, allowing users to select specific charge currents. Available options include 250mA, 500mA (default), 1000mA, 1500mA, 2000mA, 2500mA, and 3000mA.

Način pražnjenja:

The Discharge mode is used to analyze the actual capacity of a battery. It discharges the battery at a specified current.

1. Umetnite bateriju.
2. Pritisnite MODE button until 'Discharge' is selected.
3. The charger will begin discharging the battery. The LCD will show discharge progress and capacity.
4. Za nprample, a 21700 5000mAh battery discharged at 1A will take approximately 5 hours.
