one and a half times in a counter-clockwise direction to open the vent.
Note
The amber vacuum light on the front of the instrument starts blinking rapidly,
indicating the mechanical pump has powered off after a five minute period with the
turbomolecular pump off (such as when the instrument is shut down), or due to a
sustained vacuum fault lasting five minutes. When the turbomolecular pump spins down
below 50% speed due to the shut down process, the vacuum light turns off.
