I hope I am doing something wrong again.....
I connected a 15v DC power supply (Meanwell 15P1J) to the YD7001. The 15v DC is confirmed by my multimeter.
However in the YD7001 app (Build 59) the power supply window shows 19.0v and the track voltage window shows 17.8v.
My RRampMeter from DCC Specialties shows 14.1 volts on the track which is roughly what I expected.
I do recall buying a DR5000 with a 19v power supply initially since that was all there was available, but bought a 15v power supply rather than the supplied one as I run HO and not O scale. Is that a clue?
