1. Start up
•
Adjust the beam alignment in [ZOOM] mode.
•
Insert the X-ray detector.

Insert condenser aperture (2nd aperture) and minimize the swinging beam using the condenser X/Y
adjustment screws when passing through crossover.
•
Remove the any objective aperture and turn off the column pressure gauge filament by pressing the
"FILAMENT" switch.
Notice: not use any objective apertures when the detector is in! The objective aperture will generate
hard x-rays and burn out the detector.

•
Make sure to turn off the column pressure gauge and insert condenser aperture (2nd aperture).
•
Turn on the power switch of the EDS workstation.

Click "Spectral Display" icon.
•
Select "Acquire" → "Parameter"
→ "Set up". Set the max. energy to 20.48 keV.
•
Find region of interest and focus it properly with
