THT60, unless otherwise indicated. The instrument has been designed in compliance with
the directives relevant to electronic measuring instruments. For your safety and in order to
prevent damaging the instrument, please carefully follow the procedures described in this
manual and read all notes preceded by the symbol with the utmost attention. Before
and after carrying out the measurements, carefully observe the following instructions:
Do not carry out any measurements in case gas, explosive materials or
flammables are present, or in humid or dusty environments.
Do not carry out any measurement in case you find anomalies in the
instrument such as deformation, breaks, substance leaks, absence of
display on the screen, etc.
Keep the instrument steady during any measuring operation.
Do not carry out any measurements which exceed the working and storage
temperature ranges specified in § 8.1.1.
Only the accessories provided together with the instrument will guarantee
safety standards. They must be used only if in good conditions and
replaced with identical models, when necessary.
Check that the battery is correctly inserted.
Check that the LCD display gives indications consistent with the function
selected.
Do not direct the instrument at very high intensity radiation sources (e.g. the
sun) in order to prevent damaging the IR sensor.
Prevent hits or strong vibrations in order to keep the instrument from
damage.
When bringing the instrument from a cold to a hot environment, leave it on
long enough for condensation water to evaporate.
In this manual, and on the instrument, the following symbols are used:
Only use the micro SD card provided with the instrument.
Caution: observe the instructions given in this manual; improper use could
damage the instrument or its components.
This symbol on the display means that the instrument (THT60) is able to emit a
laser pointer in Class 2. Do not direct the radiation towards the eyes in order
to prevent physical damage to people.
CAUTION
Compliant with European Standards
1.1 DURING USE
CAUTION
Failure to comply with the caution notes and/or instructions may damage
the instrument and/or its components or be a source of danger for the
operator.

4.2 DESCRIPTION OF FUNCTION KEYS
The instrument has 5 function keys indicated as , , , , (THT60),
(THT47) further in the manual and a trigger key “T” with multiple functions.
4.2.1 Switching on/off the instrument
Press and hold the key for approx. 3 seconds to switch on the instrument. After approx.
20 seconds internal autotest, the instrument shows its normal measuring screen.
To switch off the instrument, proceed as follows:
1. Press and hold the key for 3 seconds. The instrument shows the following screen:
Fig. 5: Instrument switch-off screen
2. Drag the icon to the right until the end of the blue section. The instrument will
automatically switch off after a few seconds. Touch the “X” key to cancel the operation.
CAUTION
A simple pressing of the key only causes the display to switch off and
on again. The instrument also allows the display to automatically switch
off after a selected time (see § 5.2.1.2).
The instrument may take approx. 10s to switch off in case it is connected
to the external power supply.
4.2.2 Key
Pressing the
key allows showing/hiding the icons of the instrument's main menu
(operation possible also by touching the display), setting the value of the distance from the
object in Fusion screens (see § 5.1.3) and quitting the internal function screens and going
back to the main menu.
4.2.3 Key
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 it is necessary that the instrument performs its
internal calibration. It is possible to manually calibrate the instrument at any time by
pressing the key, or to let the instrument calibrate itself automatically after a certain set
time (see § 5.2.1.2).
4.2.4 Key
Press the key to automatically save the IR image shown on the display in the
instrument's memory (micro SD card) (see § 5.2.4.1).

THT47 - THT60
5.1.2 Image rotation and zoom
The instrument allows performing complete rotations (0 360°) and has a digital electronic
zoom function “x1 x20” of the framed IR image. To use these functions, proceed as
follows:
1. Touch the symbol “ ” on the display. The instrument shows the following menu at the
bottom of the display:
Fig. 7: Menu for setting image rotation and zoom
2. Press the “ ” key to activate the zoom function. The indication “0° / 1.1” is shown on
the display and the image is zoomed in 10% more with respect to the original image.
3. Touch the “ ” or “ ” keys to increase or decrease the image zoom with a
resolution of 10%. Zoom range 1.1 20.0
4. Touch the “ ” key to restore normal image view.
5. Touch the “ ” key to activate rotation. The indication “1°/1.0” appears on the display
6. Touch the “ ” key to rotate the image clockwise of the “ ” key to rotate the image
counterclockwise with a resolution of 1°. Rotation range 0° 360°
7. Touch the “ ” key to restore normal image view.
8. Touch the “OK” key to quit the menu.
5.1.3 Adjusting the distance of the object in Fusion screens (THT60)
In “IR_MIX_VIS” and “VIS_MIX_IR” display mode (see § 5.2.3.1), due to the different
position of the lens and of the built-in photo camera, when the object is close to the lens,
the visible image tends to become bigger, while the IR image tends to reduce. When the
object is more than 5m far from the lens, this effect tends to disappear The instrument
allows setting the distance of the object in order to compensate the effect at distances
shorter than 5m. Proceed as follows:
1. Select the “IR_MIX_VIS” or “VIS_MIX_IR” display on the instrument (see §). The
instrument shows the following screens:
Fig. 8: Adjusting the distance of the object in Fusion screens
2. At the top of the display, the instrument automatically shows the symbol “ ”, where
the value indicated inside the square represents the last value set for distance.
3. Press and hold for 2 seconds the key to set the value of distance of the lens from the
object. The following values are available: 1/2m (0.5m), 1m, 2m and 5m
