Hi! Those who have volt meter from @ajaynagra group buy, how do use it ? I mean it shows 0% all the time, when I press button on the back it shows volts. O.k volts are correct, but when I switch off battery, next time when I turn battery on it resets to % again. I need it to stay on volt reading all the time I don’t care about % reading.
On the back is button, but there is also another button( same but,there some parts missing) picture:
Maybe that other button is for programming? Because that first button is only change % to volts and turn off device.
