large. Larger samples can be observed at a large lowworking distance.
5.2.2.3
Vacuum the sample chamber
Click "air extraction" on the software interface, and the vacuum system will
automatically vacuum the sample chamber. When the vacuum of the sample
chamber 48 reaches the preset vacuum state, open the V1 valve and the instrument
can start operation.
5.2.3 Start electronic gun
Software control interface starting electron gun power is divided into "cold start" and
"hot start", the first start gun after replacing the filament, need to use cold start, after
the daily off electron gun restart use "hot start" to start the automatic gun program.
Note: "cold start" vs. "hot start": cold start has a 15-minute waiting time during starting
gun. Since the field emission electron source is ventd a lot when it is first used, the
vacuum may drop and it needs to wait for 15 minutes during the loading process. High
pressure HV and filament cannot be added until the vacuum degree is reached. The
vacuum and high pressure interlock system, the high pressure will be cut off
automatically when the vacuum degree is low.
5.2.4 Image acquisition
5.2.4.1 Basic operation
Click the SE button in the right control panel of the software Open the V1 block valve,
adjust the operating brightness, contrast, magnification, you can see the image in the
image window of the software control interface
