Function:

• Voltage Indicator(CV): The module is in the constant voltage mode.
• Current Indicator(CC) : The module is in the constant current mode.
• Voltage potentiometer: The multimeter adjusted to voltage is connected the module output. Adjust potentiometer clockwise, the output voltage increases. Adjust potentiometer counter-clockwise, the output voltage drops. The multimeter will display voltage. (In constant voltage working state)
• Current potentiometer: The multimeter adjusted to current is connected the module output. Adjust potentiometer clockwise, the output current increases. Adjust potentiometer counter-clockwise, the output current drops. The multimeter will display current.(In constant current working state).
