5.2.2.5 Control parameters of temperature measurement
The thermal camera allows correcting the measured value of temperature by means of the
tools (Spots, Lines and Areas) in the following ways:
Global mode the values of the control parameters associated to all tools are defined
globally.
Custom mode each tool may independently take different values of control
parameters according to the selections made by the user.
Parameter Emissivity
In order to carry out accurate temperature measurements, it is important to define the
correct emissivity value (), which represents the ability of a body to emit infrared radiation,
according to the kind of material the measured object is made of Table 2 shows the
emissivity values for the most common materials. Emissivity takes values between 0
(mirror or perfectly reflecting surface) and 1 (perfectly radiating blackbody). Most of the
painted or oxydized surfaces have an emissivity value of approximately 0.95.
Material
Material
Black body 1 00 Steel (oxidized) 0.79
Smooth carbon surface 0.98 Very oxydized copper 0.78
Ice crystals 0.98 Cotton cloth 0.77
Human skin 0.98 Sand 0.76
Slate 0.97 Non-enameled silicone 0.75
Distilled water 0.96 Oxydized iron at 100°C 0.74
Smooth ice 0.96 C20A coating 0.73
Wet ground 0.95 Basalt 0.72
Carbon soot 0.95 Graphitized carbon at 500°C 0.71
Clean glass plate 0.94 Red rust 0.70
Paint, oil 0.94 Very rusty iron 0.69
Red brick 0.75 Water 0.67
White paper 0.93 Black soil 0.66
Cement 0.97 White cement 0.65
Dry ground 0.92 Oxydized wrought iron 0.64
Rough plaster coating 0.91 Oxydized lead at 1100°Z 0.63
Associated to each control tool (Spots, Lines, Areas) there is an internal table from which
to select the emissivity value of common materials and define a custom value (see §
5.2.2.1, § 5.2.2.2 and § 5.2.2.3).
EN - 28
THT70
Parameters reflected temperature and environmental temperature
Objects with a low emissivity may reflect infrared energy coming from adjacent objects;
this energy is added to the energy of the object itself, thus causing possible measurement
mistakes. In several situations, there are sources of heat with a higher temperature than
the temperature found near the object being measured. In this case, it is necessary to
compensate this reflected energy by entering the presumed temperature value of the
adjacent heat source into the thermal camera. In most of the applications, the reflected
temperature is identical to the environmental temperature and has negligible effects on
temperature measurement on objects with a high emissivity.
Environmental temperature which can be set within the range: –40°C 125.0°C
Reflected temperature which can be set within the range: –100°C 2000.0°C
Parameter Offset
This parameter can be set if, in automatic mode, you are sure of the values which the
temperature levels associated with the colour palette must take (see § 5.2.3.3). In this
case, the levels ate increased or decreased by the quantity inserted in that field.
Offset which can be set within the range: -10°C 10.0°CParameter Distance
This parameter identifies the distance between the thermal camera and the object to be
measured. In most of the applications, the temperature levels associated to the colour
palette (see § 5.2.3.3) are influenced negligibly by small variations of distance. Therefore,
it is possible to leave this parameter set to the default value without having significant
errors on measurement. For distances higher than 300m it is possible to have variations >
1°C in temperature level.
Distance which can be set within the range: 0m 5000mParameter Relative humidity
This parameter identifies the value of relative humidity of the environment where
measurement is carried out. In most of the applications, the temperature levels associated
to the colour palette (see § 5.2.3.3) are influenced negligibly by small variations of
humidity. Therefore, it is possible to leave this parameter set to the default value without
having significant errors on measurement.
Relative humidity %RH which can be set within the range: 1% 100%

5.3 USING THE INSTRUMENT
For a typical use of the instrument, please refer to the following procedure:
1. Switch on the instrument by pressing and holding the “” key for 3 seconds. After
approx. 20 seconds of internal autotest, the instrument shows its normal measuring
screen. The instrument shows an initial screen like the one shown in Fig. 70.
Fig. 70: Initial screen
2. It takes approx. 30 seconds for the instrument to become fully operating. During this
time interval, the instrument carries out an automatic calibration and the internal
commutations may produce some noise
CAUTION
The autocalibration sequence starts when the instrument is switched on and
continues during the thermal cameras normal operation, during which the
image freezes for a few seconds in order to eliminate offset errors. The
noise produced by the commutation of internal parts is not to be considered
as a problem of the instrument.
3. Before any measuring operation, correctly focus the thermal camera in order to prevent
having grossly inaccurate measurements and a low quality of the saved image (see §
5.1.1).
4. For accurate temperature measurements, make sure the surface of the measured
object is always bigger than the surface measurable by the instrument, which is given
by the instruments field of view (FOV). The instrument has a field of view of 25° x 19°

The representation of the ratio D (distance from the object) / S (surface of the object) for
an instrument provided with 22mm lens is described below.
Fig. 72: Representation of the instruments D/S ratio
In the representation, it is possible to see how the IFOV (Instant Field Of View =
geometrical resolution of the instrument = size of the single pxl of the IR sensor) is equal
to 1.14mm at a distance of 1m of the instrument from the object being measured. This
means that the instrument is capable of carrying out correct temperature measurements at
a distance of 1m on objects with a size not lower than 1.14 mm.
5. The typical application of thermal cameras is the one in which it is necessary to detect
a temperature difference between two adjacent objects, as this kind of analysis is often
sufficient to identify anomalies in electrical and mechanical appliances, etc. In such
situations, in which an accurate temperature measurement is not strictly necessary,
emissivity value may be set to “1” (see § 5.2.2.5), it is not necessary to consider the
objects surface, its distance and the field of view). However, if accurate measures are
required (e.g. the temperature of an electric motor), it is necessary to correctly set the
parameters previously described in this manual.
6. Correctly set the temperature range of the image (see § 5.2.1), defining the adequate
values according to the MIN and MAX temperatures detected within the measured
area.
7. Frame the objects to be measured by using the laser pointer, if necessary (see §
4.2.5). The instrument displays the temperature values associated with the measuring
cursors.
8. Use the T key (see § 5.2.4.1) to freeze the image on the display and save it in the
internal memory of the instrument or on the external micro SD card. The instrument
saves the images in sequence with file name “YYMMDD_xxxxT”. Enter possible voice
(see § 5.2.4.2) or text (see § 5.2.4.3) annotations onto the saved image.
9. Touch the icon “
” to see the saved images again (see § 5.2.5).
