Maintenance Instructions
Clean the instrument between each measurement using a soft, damp cloth. Failure to clean the prism on a regular basis will lead to inaccurate results and damage to the prism's coating.

Accurate measurement depends on careful calibration with distilled water. The prism and sample must be at the same temperature for accurate results. Do not expose the instrument to damp working conditions, and do not immerse the instrument in water. If the instrument becomes foggy, water has entered the body, and the instrument should be replaced.
