EVAP2 was tapped up manually to 50A.
Vacuum tripped evap off.
Tapping back up manually now...

Tapped up manually to 45A for both TGHT and TBHT
IGP1 = 4.8e-5 Torr
Will initiate auto-ramp at 0.2A/min and 0.1A/min for the TGHT and TBHT respectively once vacuum settled down and stable.
Max setpoints set to 520A and 230A for the TGHT and TBHT respectively.
Good Vacuum = 3.0e-5 Torr. Bad Vacuum = 4.0e-5 Torr.
