5. Configuración

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. Instrucións de funcionamento

Inserción de pilas:

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.

Modo automático:

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 MODO button to select the desired function (Charge, Discharge, Cap Test, Repair).
2. Preme o ACTUAL 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.

Modo de descarga:

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

1. Insira a batería.
2. Preme o MODO button until 'Discharge' is selected.
3. The charger will begin discharging the battery. The LCD will show discharge progress and capacity.
4. Por example, a 21700 5000mAh battery discharged at 1A will take approximately 5 hours.

This image illustrates the discharge mode on the charger's LCD. This function is used to analyze battery capacity by discharging at a set current, such as 1A for the first and fourth slots.

Capacity Test Mode:

This mode measures the true capacity of a battery by performing a full charge-discharge-charge cycle.

1. Insira a batería.
2. Preme o MODO button until 'Cap Test' is selected.
3. The charger will first fully charge the battery, then fully discharge it to measure capacity, and finally recharge it to full.
4. The measured capacity will be displayed on the LCD.

This image depicts the capacity test mode on the LCD. In this mode, the charger fully charges a battery, then fully discharges it to measure its actual capacity, and finally recharges it.

Modo de reparación:

The Repair function is designed to help restore the capacity of low-voltage or older Ni-MH batteries through a series of charge/discharge cycles. This process can take an extended period.

1. Insira a batería.
2. Preme o MODO button until 'Repair' is selected.
3. The charger will initiate a repair cycle. Monitor the battery during this process.
