Do We Still Need To Do These?

Test LQ2 FuG with new polarity reversal switch.

Mount Left Shield House temperature readout in CH

Find and connect NMR cables in CH

Swap out MFCs in VDC mixing system

Possible Future Items

Remote reset for Hall C spectrometer motion (maybe next year)

Install new liquid level meters on SHMS- Install done, waiting on software and LN2 probe cal to go live (need Steven).
