With the HAM1 ion pump performing nobly, the HAM1 turbo pump was spooled down and the associated SS-500 pump cart was disconnected from the HAM1 volume.  All mechanical sources of vacuum equipment noise should be in nominal observing mode.  

The HAM1 pressure gauge, PT-100, was connected via a standard gauge pigtail cable, directly from gauge body sub-D to supply CPC.  All of the temporary cabling was removed including the breakout board and analog voltage readout pigtail, so PT-100 is solely on Ethercat communication.
