Lens Cleaning
The user should periodically clean the instrument’s front window.
A dirty front window (lens) can cause temperature measurement errors. The window is fragile, and
care should be taken when cleaning it to prevent scratching. Use camera lens or eye glass tissues to
clean the window.
Periodic cleaning can be done by completing one or more of the following in one of the following
ways:
•
Blow loose particles off the front window with clean compressed air.
Note: Unfiltered compressed air, as well as user’s own breath, can cause condensation on the
front window, which can trap dust particles instead of removing them.
•
Gently brush off particles with a soft camelhair brush.
•
Thicker contaminants can be cleaned with water and a camera lens tissue.
•
Fingerprints and grease can be removed either with isopropyl alcohol, Ethanol, Xylene,
Acetone, or Kodak
