8.1 Mode of operation
All objects with a temperature above absolute zero radiate infrared energy, which extends in every direction
with the speed of light. If an infrared thermometer is trained on an object, the lens gathers the energy and
focuses it on an infrared sensor.
The sensor responds by emitting a voltage signal which is directly proportional to the absorbed energy. The
microprocessor-controlled electronics in the unit are able to ascertain and display the current temperature
(in regard to a wider parameter).
Objects with radiant or polished surfaces not only radiate energy but also reflect a proportion of radia-
tion from their surrounding area. A factor between 0.1 and 1.0 designated as the emission level makes
allowances for this factual calculation so that only the true radiated energy, and not the reflected energy, is
consulted for calculating the measured value. The majority of applications are measured with an emission
level of 0.95.
In the Ex-MP4 a the level is set at 0.95 and cannot be altered.
