Question: To set the cold control pressure, the WSM gives mightyvac readings as "340-420 mbar / 350-450mmHg). However, my mightyvac has "in.Hg" and "kpa." I figured mmHg stood for millimeters and "in.hg" stood for inches, so I did the conversion and it came out to 13.4 - 16.5 inches. I pulled 15 in.Hg on the mightyvac when setting the cold pressure on the WUR.
Am I right in assuming mmHg = millimeters and in.Hg = inches?

I think you have the vac conversion right, maybe MPDANO can do a quick verify as his super deluxe vacuum pump shows both inches and millimeters on the gauge.
Just want to make sure, when you set the cold control pressure to 2.1, you did it by tapping on the post up or down as required and not by turning the allen screw in or out right?
