9. Maintenance
The accuracy of measurement is affected by dust or dirt on the surface of
the infrared lens. Prevent dirt or dust from adhering to the surface of the
lens during use or storage.
When removing dirt from the infrared lens, use a blower for camera
lenses. If stubborn stains persist, clean the surface of the lens softly with
a swab moistened with lens cleaning liquid.
Note: Never clean the infrared lens with water or detergent. Doing so may affect the performance
of the lens and cause inaccurate measurements.
