Wiring
From factory, Vext is connected to VCC.
To power the meter from an independent source, you will need to unsolder a jumper inside the meter. Once done, you can power the meter from an independent source.
Useful Functionality
LOP
LOP is under voltage protection. When the output voltage drops below the setting, the meter will automatically cut off the output, and the output indicator will change from green to gray.
