9. Functional description / Operating instructions
Please read this operating manual through carefully so you
can familiarise yourself with all of your Lasertemp's functions
and be able to use them. For your safety and information,
read the notices on the following pages!
9.1. Working method
All objects with a temperature above absolute zero radiate
infrared energy that spreads outward in all directions with
the speed of light. When an infrared thermometer is pointed
at an object to be measured, the lens collects the energy
and focuses it on an infrared sensor. The sensor reacts by
outputting a voltage signal that is directly proportional to
the energy received. By including additional parameters,
the microprocessor-controlled device electronics are able
to determine and display the current temperature.
Objects to be measured that have a glossy or polished
surface do radiate not only energy, but also reflect part of
the radiation from their environment. A factor described as
emissivity between 0.1 and 1.0 takes this fact into account,
so that only the energy genuinely radiated (and not reflected)
is involved in calculating the measurement value.
