The object being measured should be larger than the spot size as illustrated in the distance to spot diagram. Measurement considerations: If the surface of an object to be measured is covered with frost, dust or other materials, surface cleaning must be performed before accurate measurements can be made. High Reflective Surfaces: If the surface of an object to be measured is highly reflective with a very low emissivity value, apply masking tape or apply flat black paint to the surface to raise to improve the accuracy of the measurement.
