I ran into a "snag" with the RGA reconfiguration that I had envisioned and won't be able to pump the volume seen by PT246B until next week -> The pumping effect provided by the gauge isn't enough to match the out gassing and the pressure is rising as well as the rate of rise -> If it starts to "run away" I'll have to shut it off but, ideally, it will stay in its safe operating pressure range until I can pump it early next week.
