7.
Slide sample holder onto stage dovetail. Note proper direction to slide on “dovetail”
relative to step on stage platform.
8.
Adjust sample height (Working Distance) using height gauge. 10 mm is the EDS
working distance. Bottom end of ruler corresponds to the working distance (see
photo). Adjust the ruler position in the height gauge for desired working distance.
No part of the sample should extend above the ruler end
. A 10 mm W.D. should
be used for nearly all work except low magnification imaging or if you need to tilt
more than 15 degrees. Working distances up to 48 mm can be used to attain
magnifications as low as 5x and/or better depth of focus. Working distances shorter
than 8 mm should never be used! A barrier has been installed to prevent inserting a
sample set too high.
