Open or close the output: press ON/OFF button in any state to open or close the output, loop in turn, and close the output when the digital tube has "OFF" display instructions
Switch input and output display: IN the non-output voltage current setting state, press the "IN" key or "OUT" key to switch to display input voltage and output voltage. When the input voltage is displayed, the "IN" indicator will be lit at the same time, indicating the output voltage, and the "IN" indicator will go out
CC and CV instructions: the module works under constant pressure or constant current state, and the CC and CV indicators will be lit accordingly to indicate CC and CV status
The output current shows zero point calibration: in the no-load condition, the SET key is not put on the power, and the output current shows zero calibration. The calibration will automatically exit the calibration process and release the SET key
Set data automatic storage: in the process of keystrokes, digital tube display state, output voltage and current data, switch output status will be automatically stored memory, next time electricity work are stored by default state
