Description

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

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.
