...

• Start: Turns on the high voltage which generates an electron beam. Must press start to generate an image.
• Fast: Image updates quickly. Useful to select 'Fast' while changing Field of View.
• Slow: Image updates slowly. If in calm sea state, can produce a higher quality image. 
• Reduce: Takes just the center portion of the screen to update. 
• Freeze: Stops updating the image and preserves the image as it was at the time of pressing Freeze. 
• Magnification: Control to increase or decrease magnification. Ranges from x40 to x30,000.
• Auto B/C: Click this to automatically adjust the brightness and contrast of the image.
• Auto Focus: Click this to automatically focus the image. Image Mode: 
• 5 kV / 15 kV / Analy: Sets the beam voltage between either 5kV, 15kV, or Analy
• Quick Save: Saves the current image on the screen. Captures a lower resolution image of 640x520 pixels.
• Save: Re-captures the image and saves it at a higher resolution image of 1280x1040 pixels.

Storage convention for SEM files on the local PC:

1. SEM
2. Site
3. Hole
4. Sample

E.g.
Folder SEM
Folder 1431
Folder 1341A
Folder U1341A_1_H_1_1-11cm (all files for this SEM sample)

NOTE:  All files need to be moved to USERVOL and DATA1 by the end of the expedition.
