  1. Power-on the host PC, and then log in to Windows.
  2. Power-on the LC and let it initialize.
  3. For a Xevo TQ-S, TQ MS, or TQ-XS, ensure that the MS power cord is plugged in and that both toggle switches on the back (middle-bottom) are in the up position. For all other triple- or single-quads, power on the MS using the power button power button.PNG.
  4. Wait five minutes.
  5. Start up MassLynx and open the Tune page.
  6. From the Tune page, pump the instrument down using vacuum (from the top drop-down menu in the middle of the page) and select pump. The MS pumps down faster if the isolation valve is closed and the argon or CID/trap gas is on. Be sure to open the valve before going into Operate mode.
  7. For the most reliable results, it is best to let pumping continue overnight before running, especially if the system was vented for a while (days).
