I wired in a 220 circuit just for the bench and I bought and automatic depression control from a Bruce but I will never install it because I don’t want to rewire the bench. Bruce has the software program that I use on his forum. What made me build this bench is I bought one years ago that used electronics like this but it was huge in size, and low in power. It tested at 10 inches and converted to 28 inches. l bought another bench that used two fluid manometers but being fluid it was constantly changing with weather and the barometer. So I built one that is totally electronic on reads the same at -20 degrees or 100.
