Maintenance
NOTICE
Use nitrile gloves to handle the window and handle it by the rims only. (Avoid touching the
window surfaces even when wearing gloves.)
c. If the window is still usable, grasp it by the plastic ring and carefully place it in the provided
package (with desiccant). Store the package someplace that is clean and dry.
4. Install the new window.
a. Grasp the new window by the plastic ring and carefully place it in the window replacement tool
with the window threads facing up.
b. Rotate the window until the three notches in its outside rim line up with the ribs on the tool’s
inside rim.
c. Reversing the removal procedure above, tip the tool and window just enough to place the
window over the opening in the spectrometer.
d. While maintaining light pressure against the spectrometer wall, slowly turn the tool clockwise to
ensure the window’s threads are engaged properly.
NOTICE
The window should turn easily at the start; if it doesn’t, reverse the direction of rotation and
restart the insertion to avoid stripping the threads.
e. Continue rotating the tool clockwise until you feel the O-ring compress, plus 1/8 turn more.
5. Repeat steps 3 through 4 above to replace the second window.
6. Turn on the instrument power, connect to your computer, and start OMNIC Paradigm software.
7. Verify the spectrometer’s performance.
