1) MS Tune page, Bottom right corner, Vacuum status, Vacuum OK or Vented.

2) MS Tune page, Diagnostics Tab, Turbo Speed 0% = vented; 100% = pumped down.

3) MS Tune page, Diagnostics Tab, Pumping Status LEDs, blue when pumps are off, green when pumps are running.

4) MS Tune page, Diagnostics Tab, Source Interlock LEDs, 2nd LED is red = Turbo <80%.

5) ACQUITY MS Console, System Status: "Turbo Pump OFF".

6) ACQUITY MS Console, Xevo TQ-S Status: "Turbo Pump OFF".
