Before measuring
• Ensure that the surface to be measured is free of
dust, dirt or similar substances.
• To be able to gain exact measurement results on
surfaces which reflect heavily, stick matt masking
tape to the surface or apply matt black paint with a
very high and known level of emissivity.
• Note the 20:1 ratio of the distance to the measuring
spot size. The larger the distance to the object, the
larger the measuring points size and hence, the less
precise the measured result.
