Description of touch points：
The charger has 6 touch points, including mode selection point (MODE), current selection point (Current), independent selection and viewing data point (1234), and LED light prompt, making it simple and convenient to use;
2. MODE: Mode selection; Including CHARGE charging mode, DISCHARGE discharge mode, and TEST capacity detection mode;
Current: current selection; Including charging 500mA/700mA/1000mA/200mA, discharging 250mA/500mA;
3.1/2/3/4 channel touch points: corresponding to 1-4 channel situations; Independently select and view data, long touch any point to control the LCD screen display;
4. In any case, after long touching the "beep" prompt sound of the MODE button, the CHARGE mode, DISCHARGE mode, and TEST mode can be changed. Then, within 8 seconds, lightly touch the corresponding function touch point to change the mode, current level, independent, mixed charging, and capacity detection functions. After selecting it, it enters the working state for 8 seconds. In the working state, lightly touch the (1234) touch point, View the reference values of current (mA)/capacity (mAh)/voltage (V)/time (h) data.

Mode operation instructions:
When the charger is connected to the power, the LCD screen of the charger will instantly turn on all lights, and the 1/2/3/4 channel LED light will prompt red and green to enter the ready state. If the battery is not inserted, it will display "null". If it is a bad battery inserted or the battery is reversed, it will display "Err". The red LED light for normal operation of the battery will always be on, and the green LED light for fully charged or stopped charging will always be on;

CHARGE (charging mode)：
1.1 When the charger is inserted into the battery and connected to the power supply, the system automatically enters charging mode (CHARGE). The charger automatically defaults to charging current of 500mA. Within 8 seconds, you can select 500mA, 700mA, 1000mA, or 2000mA current through the current touch point (Current) to charge. After 8 seconds, the system will lock the selected current for charging. If no setting is made within 8 seconds, the system automatically defaults to charging at 500mA current, At this point, the current and other functions cannot be changed. If changes are needed, long touch the MODE button to reselect;
1.2 In charging mode (CHARGE), independent charging or different current selection can be changed within 8 seconds, as well as mixed charging of different batteries; The operation is simple. Within 8 seconds, lightly touch the corresponding touch point of the 1234 battery, then touch the MODE to change the mode, and touch the Current point to change the current, independent, mixed charging, and capacity detection functions. After 8 seconds of selection, it enters the working state. Pay attention to selecting the charging current based on the size of the battery capacity. If fast charging is not necessary, it is recommended to use 500mA charging, which is the safest;
In 1.3 charging mode, by lightly touching the 1234 touch point, you can switch and view four parameters: charging capacity (mAh), charging time (h), charging current (mA), and voltage (V). After the battery is fully charged, "End" will be displayed;
(Note: When using a 2000mA current for charging, only two channels can be used for charging. If there are more than two channels, the system will automatically reduce the charging current of the channel using 2000mA charging to 1000mA current for charging.)

DISCHARGE：
2.1 After the charger is inserted into the battery and connected to the power supply, touch (MODE) to select (DISCHARGE discharge mode) within 8 seconds, and then touch (Current) to select the desired current (250mA or 500mA). If there is no current selection, the system will automatically default to a discharge current of 250mA. After 8 seconds, the system will lock the current you have selected for operation. The system will record the data during discharge to detect the battery discharge capacity.
2.2 Refer to the table below for the discharge process:
Enter DISCHARGE
Вход  DISCHARGE selected discharge current
Выбор разрядного тока Battery discharge
Разрядка батареи         END

TEST (Capacity Detection Mode)：
3.1 TEST mode: It is to first fully charge the battery, then discharge the battery and record the discharge level and other parameters, and then automatically fully charge the battery while recording the charging level and other parameters. Test the battery capacity from both discharge and charging aspects. Refer to the table below for the capacity testing process:
Enter TEST
Вход  TEST Selected Current Charging
Выбор зарядного тока Battery charging
Зарядка батареи Battery discharge
Разрядка батареи Recharging
Повторная зарядка         END
3.2 Under any state, the prompt sound of long touching the MODE "beep" can enter the TEST mode;
3.3 After entering the TEST mode, within 8 seconds, you can select 500mA, 700mA, 1000mA, or 2000 mA current through the current touch point (Current). After 8 seconds, the system will lock the current you have selected. If no setting is made within these 8 seconds, the system will automatically lock the 500mA current for charging (the selected current is the default charging current for the system) (Note: NiMH batteries do not have a 2000mA current range)
3.4 When the battery is fully charged, the system automatically switches to discharge, with a fixed discharge current of 500mA, and records the discharge data to detect the battery's discharge capacity.
3.5 After the battery is discharged, the system automatically switches to charging. The charger will charge the battery again with the previously selected current parameters and record the charging data to detect the battery's charging capacity. At this point, the system displays "END" and stops charging.
(Note: When using a 2000mA current for charging, only two channels can be used for charging. If there are more than two channels, the system will automatically reduce the charging current of the channel using 2000mA charging to 1000mA current for charging.)

USB 5V output：
USB is only used as a 5V mobile output with an output current of 1000mA;
Must be connected to the power USB output to be effective; At this point, the 5V electronic product can be powered on;
Without connecting to the power supply and only discharging the battery, the USB output is invalid.
