Has anyone had any issues with the Agilent 5975 MS showing HiVac 0.00e+00 when doing an autotune? My baseline has been noisy so when I did an autotune, the baseline got worse and I noticed pressure for the HiVac was showing 0.

The autotune looks good. The number of peaks in the spectrum is a little bit high (typically less than 150) but that's the only glaring problem I see. The HiVac reading 0.00 may be because the gauge itself has failed. Does it say this value all the time? On the 5975 display, it may switch between 9.99e-09 and 1.00e00 or something similar. Also look at the gauge itself at the back of the MSD if possible. The ready light will be red instead of green.
I will mark this as assumed answered, please feel free to update us on the results.
