Data automatic storage: in the process of key, digital tube display state, output voltage and current data, the switch output state will be stored automatically, and the next power work will be stored as the default state
Display zero calibration: in no-load condition, the setting key is not placed on the power supply, and the output current is shown as zero scale. The calibration will automatically exit the calibration process and release the setting key
CC and CV instructions: the module works under constant pressure or constant current state, and indicates CC and CV status according to CC and CV indicators
Input and output display: IN the non-output voltage current setting state, press the "IN" key or "out" key to display the input voltage and output voltage. When the input voltage is displayed, the "IN" indicator is also lit, indicating the output voltage, and the "IN" indicator will be extinguished
Open or close the output: press/close the button in any state to open or close the output, and the loop closes in turn, closing the output when the digital tube has a "close" display command
