8. Operating Instructions

Infrared thermometers measure the surface temperature of an object. The
device cannot measure through transparent surfaces like glass. It would
measure the temperature of the glass surface. Cover the surface using a black
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.
