4.2. DESCRIPTION OF FUNCTION KEYS The instrument has 8 function keys described further in this text and a trigger key “T” with multiple functions.

4.2.1. Switching on the instrument

1. Press and hold key

for 2s to switch on the instrument. After the initial splash

screen is displayed (see Fig. 5 ­ left side), the instrument needs for a certain heating

time (approx. 30s) in order to provide accurate temperature measurements and quality

images.

2. The instrument initially shows the visible image for a few seconds and the message “IR

calibration…” while it correctly calibrates the internal sensor (see Fig. 5 ­ middle).

3. After a few seconds, the IR image is shown on the display and the instrument is ready

for measurement (see Fig. 5 ­ right side).

Fig. 5: Sequence upon switching on the instrument
CAUTION

· The sound that accompanies the message “IR calibration…” is a

necessary condition for the instrument’s internal calibration.

· Pressing the

key allows switching on/off the instrument. The

instrument also has an Auto-Power-Off function with selectable time.

4.2.2. Switching off the instrument

5.2. IMAGE FOCUSING Focusing the IR image found on the instrument display must be performed manually by rotating the lens installed on the IR sensor (see Fig. 1 ­ Part 3). Keep the instrument steady while performing this operation.
CAUTION
· Always focus the image before saving it, in order to perform correct temperature measurements of the framed target.
· The IR image on the display may be out of focus after a few minutes or if a new object is framed. In order to solve this problem, the instrument performs its internal calibration and makes a sound which must be considered as fully normal.
Fig. 8: Focusing the image on the display The correct focusing of the image allo ws for the whole of the infrared energy irradiated by the target to be directed at the pixels of the IR sensor. Without focusing, the thermal image may be out of focus and the indicated radiometric data will be inaccurate.

Setting Emissivity of the material
1. Touch item “Emissivity” to set the emissivity values of the item whose temperature needs to be measured. In order to carry out accurate temperature measurements, it is important to define the correct value of this parameter, which represents the ability of a body to emit infrared radiation, according to the kind of material the measured object is made of. Table 1 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.

5.3.5. Menu Parameters In this menu it is possible to set the value of the following correction parameters, necessary for a correct temperature measurement to be performed by the instrument:
Material emissivity see § 5.3.1.2 Ambient temperature Reflection temperature Relative humidity Temperature compensation (offset) Distance from target
Parameters reflection temperature and ambient 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 reflection temperature is identical to the ambient temperature and has negligible effects on temperature measurement on objects with a high emissivity.
Ambient temperature which can be set within the range: -10°C ÷ 50°C Reflection temperature set within the range: 0.0°C ÷ 650.0°C (THT500, THT600, THT600L) Reflection temperature set within the range: 0.0°C ÷ 1200.0°C (THT500H, THT600H)
Parameter Temperature compensation (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 § 5.4). In this case, the levels ate increased or decreased by the quantity inserted in that field.
Offset which can be set within the range: -5.0°C ÷ 5.0°C
Parameter 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 § 5.4) 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 ÷ 2000m
Parameter 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 § 5.4) are influenced negligibly by small variations of humidity.
EN – 37

THT500x – THT600x

5.4. ADJUSTING THE IMAGE TEMPERATURE The instrument allows adjusting the temperature associated with the framed image on the display (levels high, low and span) as follows:

Automatic (AUTO) mode the minimum and maximum temperature levels of the framed object on the display and associated with the colour palette are automatically defined by the instrument and dynamically vary when moving it. This (default) option, which can be used in most cases, allows for an optimum display of the IR image. The relationship between temperature and colour of the palette is linear.
Histogram (HG) mode the minimum and maximum temperature levels of the object framed on the display are always defined automatically by the instrument, as in the Auto mode, but in this case, the areas of the image in which temperature values are very different from the values of adjacent areas are highlighted. The relationship between temperature and colour of the palette is non-linear according to a histogram algorithm. This mode emphasizes image display in very dark working environments.
Manual (MANUAL/LOCK) mode the minimum and maximum temperature level of the framed target on the display are manually set by the user. This mode, particularly useful to clearly identify only some areas of the image, is recommended in case of advanced thermographic operations.

1. Press key

or touch the icon “AUTO” found at the bottom on the right side of the

display. The screens in Fig. 46 show the selection of modes “AUTO” and “HG”.

the external monitor or device. 6. At the end of the operations, switch off the external monitor or device and disconnect
the video cable from the instrument.
5.7. CHARACTERISTICS OF THE LENS The instrument is provided with a 22mm focus lens (THT600, THT600H), 38mm (THT600L) or 9mm (THT500, THT500H). The theory of operation is reported below, based on the 22mm lens.
Definitions
FOV (Field Of View) Visible range represents the maximum angular opening (expressed in degrees) the instrument is capable of managing at a certain distance.
IFOV (Instantaneous Field Of View) represents the smallest detail within the FOV, that the instrument can detect at a certain distance. It is expressed in radians by the following formula:
IFOV (theoretical) = (size of sensor’s pixels) / (focus length of the lens)
D:S ratio Ratio Distance / Cross-section of the target object it provides information on the maximum distance between the instrument and the target having a certain cross-section (spot) in order to obtain correct temperature measurements. It is expressed as:
D:S (theoretical) = 1 / IFOV (theoretical)
Case of instrument THT600
FOV = 17° (Horizontal) x 12.7° (Vertical) Focus lens = 22mm Size of sensor’s pxls = 17µm IFOV (theoretical) = 17µm / 22mm = 0.77mrad D:S (theoretical) = 1 / IFOV (theoretical) = 1298:1
EN – 46

THT500x – THT600x
Fig. 53: Representation of the THT600 instrument’s field of view FOV Typically, the IFOV parameter (real) is always considered as approx. 3 times higher
than the theoretical one, therefore the D:S ratio (real) is approx. 3 times lower than the theoretical one. This means that, for THT600: D:S (real) ~ 433:1 5.8. USE OF THE SCREENING MODE 1. Switch on the instrument. 2. Set the emissivity parameter to a value between 0.95 and 0.98 (typically 0.95). 3. Activate the “Screening” mode (see § 5.3.1.2). 4. Activate the alarm condition (see § 5.3.1.2) and set the maximum temperature threshold associated with one of the measuring cursors (see § 5.3.6). 5. Activate the Face mode (see § 5.3.2). 6.
