(2)  Loading a Specimen

(b)  Using the handles on both sides of the specimen stage, push the stage into the chamber. 
 
(c)  Set the specimen height and specimen size 
(2) Setting the Specimen Height and Specimen Size 
 
IMPORTANT:  Do not touch the operation parts such as gears and driving screws and note that 
clothes are never placed when you bring the hand close to the movement 
mechanism in the specimen stage by the specimen exchange, etc. 
 
IMPORTANT:  The height of a specimen should be measured with great care.    Be sure to set 
the specimen size and height on the Stage Control menu.    If they are not 
properly set, when the specimen is tilted or Stage Z is small, the specimen can 
touch the objective lens or the backscattered electron detector that is provided 
on the underside of the objective lens, potentially causing damage to the 
specimen, objective lens, and backscattered electron detector. 
 
(d) Press the EVAC button on the front EVAC Panel located on the front side of the main 
unit or click EVAC located in the upper right section of the Control Panel. Evacuation of 
the specimen chamber then commences. After approximately 2 minutes accelerating 
voltage can then be energized.

  CAUTION:  When inserting the stage into the specimen chamber, be careful so that your 
fingers will not be caught between the stage and the specimen chamber. 
 
IMPORTANT:  When evacuating the chamber, be sure to hold the stage tightly against the 
chamber to ensure a tight fit before turning the evacuation process on. 
Evacuation cannot take place unless the specimen stage has a tight fit with the 
chamber.
