1. UP: short press to switch display input/output voltage; long press to enter calibration interface.
2. DOWN: short press to switch display current/power/capacity/energy/time
3. SET: long press to enter setting interface
4. ON/OFF: short press to turn on/off output; in the voltage current displaying interface, long press to set the power on output status (-ON-: power on output default on, -OFF-: power on output default off); in the capacity/energy/time displaying interface, long press to clear the corresponding data.
