3 PREPARATION FOR USE
3.1 INITIAL CHECKS
Before shipping, the instrument has been checked from an electric as well as mechanical
point of view. All possible precautions have been taken so that it is delivered undamaged.
However, we recommend generally checking the instrument in order to detect possible
damage suffered during transport. In case anomalies are found, immediately contact the
forwarding agent. We also recommend checking that the packaging contains all
components indicated in § 7.5. In case of discrepancy, please contact the Dealer. In case
the instrument should be replaced, please carefully follow the instructions given in §. 0
3.2 INSTRUMENT POWER SUPPLY
The instrument is supplied by a 1x7.4V rechargeable Li-ION battery and AC mains power
supply, which also provides for the recharge of the mentioned battery. Both of these
systems are provided with the instrument. For battery recharge, please refer to § 7.2.
3.3 STORAGE
In order to guarantee precise measurement, after a long storage time under extreme
environmental conditions, wait for the instrument to come back to normal condition (see §
8.1.1).

4.2 DESCRIPTION OF FUNCTION KEYS
The instrument has 5 function keys indicated as , , , , 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
xA 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).
xThe 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).
THT60 - THT70
EN - 10
4.2.5 Key

instrument. A small red circle “ ” is found in the middle and on the top left-hand side of
the display. Releasing the key automatically deactivates the laser pointer.
Simply press the “ ” key to activate/deactivate the built-in illuminator with white LED light.
The symbol “ ” appears in the top left-hand part of the display.
4.2.6 T key (Trigger)
Pressing the Tkey found in the front part of the instrument allows freezing (Hold) the IR
image on the display and automatically opens the section for saving the image (see §).
The symbol “ ” is found in the top part of the display. Press the Tkey again to save the
image and quit the Hold status.
4.2.7 Mounting of optional lens
For the mounting of focal optional lens proceed as follows:
1. Rotate the lens locking/releasing mechanism (see Fig. 2 – part 9) in counterclockwise
from “ ” position to “ ” position
2. Pull outward to remove the mounted lens
3. Insert the new lens taking care to the position of internal terminals applying a slight
pressure on it
4. Rotate the lens locking/releasing mechanism (see Fig. 2 – part 9) in clockwise from
“”position to “ ” position
5. Check the correct recognition of the lens on the instrument (see § 5.2.2.4)

5.1.1 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 - Pos.1). 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 object.
THT60 - THT70
EN - 12
5.1.2 Image rotation and zoom
The instrument allows performing complete rotations (0 y360°) and has a digital electronic
zoom function “x1 yx20” 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 y20.0
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° y360°
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
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
