Been searching thru the forum on how to wire up the volt meter ....cant really tell what pole is what but assuming the writing on the top left is a legend I assume the red wire would be the 5V+ and the black is the 5V-grd. is this correct??
You've got the red and black wires connected to the AC (signal) inputs and no the +5VDC and DC GND. +5VDC and DC GND are the first two connection points from left to right in your photo. The last two are the AC (siginal).
