Adhered temp recorder to Y2 BT -> Dumped unpumped volume seen be PT246 dead space into RGA assembly at port Y2-1 -> Isolated turbo pump from RGA -> Opened 10" gate valve -> Energized PT246B (eventually had to "tap" lightly with wrench to get gauge to fire) -> RGA scanning in Faraday MID, amus 2,5,14 and 28 -> will isolate Y2 BT from ion pump tomorrow by hard-closing GV11 and GV18  

This exercise is part of the Y2 pressure accumulation data collection
