adhesive tape to compensate for this. Give the adhesive tape some time to
assume the temperature of the test object and then measure the temperature
of the adhesive tape. Contaminated optics (for e.g., by smoke, dust or vapour)
affect the accuracy of the measurement.
If the distance between the measuring device and the test object increases,
the measured area becomes correspondingly larger. The relationship between
the distance and measured area can be seen in the graph below.
Ensure that the area to be measured of the test object is larger than the
measuring point. The smaller the test object, the smaller must be the distance
to the measuring device. The test object should be at least twice as large as
the measuring point to get an accurate measurement.
Emissivity
The emissivity describes the energy-emitting properties of materials.
Most of the organic materials (90%) have an emissivity of 0.95 (preset in the
device).
