Turbos was started around 4pm. Later it was found that the manual valve for the two turbo pumps on the service cap was closed. The valve was open
and pumping resumed. The roughing vacuum was high and increased into Saturday morning. The vacuum system was switched off on Saturday.

Service cap leak checked this afternoon. Found multiple leaks of 10E-8 to 10E-7 range. Connected to the backing line with IG1 at ~4E-6 T, CG1A around
40 mT. Got responses around large round flange on top, rectangular side panels, water f/t on GND and water f/t on HV. Will resume leak checking tomorrow
to attempt to pinpoint sources of leak more accurately.

Conducted a more thorough leak check this morning with Edi. He found a leak on the base of the  blue F/T insulator for the multi-pin connector (see
attachment). I discovered that all the bolts could rotate freely in the threads as they were too small. The bolts were replaced. The leak rate was reduced
but still significant. The o-ring will likely need to be replaced.

 It was found that the conversion from voltage to vacuum (Torr) in EPICS is not correct for the XGS-600 controllers in use at the TCS. EPICS did
not correspond to local values displayed on the controller. An e-fault has been submitted.
