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.
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.
