AIR EVACUATION SYSTEM

Before loading a sample, air must be allowed into the chamber to receive the vaccuum. After this is accomplished, the specimen stage door can be opened.

To evacuate the air, click on the yellow air evac button on the lower left side of the above graphic. Notice how the gauge above shows the pressure going down and the low light is on.
