picked up 3 volt meters to display the voltage of my 3.3v 5v and 12v voltages on my computer but couldn't get the volt meter to start on 3.3v noticed a solder bridge on the volt meter figured I would remove it and now I have the 3 wire version of the volt meter and can supply 5v the the red and black wire and connect white wire to the 3.3v line of the power supply and get the voltage on the 3.3v rail of the power supply
