1 – Before Beginning
Before Using the roduct, we suggest to read carefully this manual, moreover once you learned to use the instrument we
suggest always to make some test to familiarize with its functions, and only after being mastery of its use going on with the
real using.

RECURRENT TECHNICAL TERMS GLOSSARY:
Term Meaning Abbreviation or Exam le
Target
With this term it is identified the oint
of the measurement, that is the body,
the roduct or the oint we intent to
make the measurement.
S ot
This term indicates the area, circle of a
variable diameter, in function of the
distance, inside which the instrument
receives the instrument infrared
radiation, which allows to make the
measurement of the average
tem erature
Attention the sha e of the S ot is
circular when the instrument is
ositioned vertical on the Target, but in
case the instrument would be
ositioned oblique, the S ot sha e will
be elli tical
O tical Ratio
The o tical ratio indicated by two digit
divided by two oints (12:1) indicates
the ratio between Distance of the
TARGET and Diameter of the SPOT
which the o tical of which is rovided
the instrument allows, it is very
im ortant to have clear this conce t to
be able to obtain always reliable
measurements, but over all really
re resentatives of the Target
Let’s do an exam le: with O tical Ratio
12:1, it means for instance that at the
Distance of 1200 mm the S ot will have
a diameter of 100 mm (Fig. 1), and at
the distance of 12 meters the s ot will
have a diameter of 1 meter, of course
this ratio is true also for intermeddle or
su erior measures to the mentioned
values.
Laser Pointer
The Laser ray is used only to sim lify
the measurement ointing, allowing
identifying with recision the exact
oint where the o erator is making the
measurement, and it is not used at to
make the measurement, which uses
just the infrared radiation.
It is im ortant to remind that the little
red oint of a constant diameter
identifies sim ly and indicatively the
centre of the measure S ot, and it is
not the only oint where the measure is
done, while the diameter of the s ot is
variable in function of the distance as
above ex lained
Wavelength
Or
S ectrum Res onse
The Wavelength of an instrument is in
few words the frequency range inside
which the instrument obtains the
infrared radiation which later it
transforms in a tem erature value
This kind of thermometer, obtains a
radiation of electromagnetic waves
exactly as the radio we listen in into the
car, where the variation of frequency
determines a different emitter radio to
be listen, the difference between the
radio and the thermometer is that this
last one instead of an antenna has got
an infrared sensor and that instead of
the music, it retransforms the received
energy by the sensor in a tem erature
value, the wavelength determines the
range inside which the instrument is
o erative. To be noticed that inside the
infrared range there are several
different range more restricted which
ty ically are indicated as lus or minus
right to s ecific a lication and to
define also the working tem erature
level.
