Function           

• Operating mode description                                                                 

                          With key off function, and reduce power consumption.          

                  Power state can be freely defined            

                  Input and output voltages can be displayed alternately  

                  On/0ff output status, high level means output off, low level means output on. (note: high level (3.3v), the maximum output current 5mA) 

• Output voltage mode:   Boot default display it, LED indicator off                     
• Input voltage mode:      Press button switch to it , LED indicator on        
• Alternating mode :          Press button again input/output voltage alternately display (3s). Press button again, switch to output voltage display  

Memory mode  :                

• Stop working mode

               Keep pressing the button until the monitor does not display numbers ( long press more than 4s) and release the button. LED lights and module shuts down. The output voltage is zero. At this time, it does not perform memory function. ON / OFF output high level (3.3V), then the static power consumption  is about 2mA. Click the button, the module starts working again.
