keyword=3He Ref. Cell Problem Hypothesis
I think the problem with the 3He Ref. Cell fill is that the regulator on the 3He bottle is too high. Then when I tried to vent, the vent line is of course evacuated so it immediately went to nearly <0.1 atm. So venting won't work unless the line is filled with 3He. The regulator should be adjusted if you want a low pressure run. And you should never vent 3He unless you want to go to vacuum.
