1 PRECAUTIONS AND SAFETY MEASURES
In the whole manual, the word “instrument” generically indicates models THT45W and
THT46, 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 ut most 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 § 9.1.1.
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:
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 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 or be a source of danger for the operator.
Use the instrument only in the temperature ranges indicated in § 9.1.1
1.2 AFTER USE
When measurement is complete, switch off the instrument. If you expect not to use the
instrument for a long period, remove the battery.

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 §
8.5. In case of discrepancy, please contact the Dealer. In case the instrument should be
replaced, please carefully follow the instructions given in §. 10
3.2 INSTRUMENT POWER SUPPLY
The instrument is supplied by a 1x3.7V 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 together with the instrument. For battery recharge, please refer to §
8.2.
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 §
9.1.1).

4.2 DESCRIPTION OF FUNCTION KEYS
The instrument has 8 function keys indicated as , , , , , , and a trigger
key “T” with multiple functions.
4.2.1 Switching on/off the instrument
Press the button to switch on the instrument. After approx. 10 seconds internal autotest,
the instrument shows its normal measuring screen. To switch off the instrument, press and
hold the key for 2 seconds.
CAUTION
A simple pressing of the key activates the manual calibration of the
instrument, which is necessary if the IR image is out of focus or if you frame a
new subject. The message “Calibration…” is shown on the display for some
seconds.
4.2.2 Keys e
By pressing the keys or you can respectively Zoom in or out the image on the
display (see § 5.1.2). The same keys are also used for the selection of system parameters.

5.1.1 Image focusing
Focusing the IR image found on the instrument's display must be performed manually by
rotating the adjuster installed on the front part (see Fig. 2 - Pos. 12). 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.

THT45W-THT46
5.1.2 Image zoom
The instrument is provided with an electronic digital zooming function of the IR image and
of the framed visual image. To use this function, proceed as follows:
1. Frame the object to be tested (see Fig. 6 – Left side) and press the key as many
times as you want to zoom the image. Each pressing increases the size of the image
by 10% with respect to the original. The instrument show the zoom value on the top
side of the display (see Fig. 6 – Right side relevant to x10 zoom). Possible options are:
1x 32x
Fig. 6: Setting image zoom
2. Press the key to zoom out until you go back to the original image.
5.1.3 Adjusting the distance of the object in Fusion screens
In “Fusion” display mode (see § 5.2.4), 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 2m 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 2m. Proceed as
follows:
1. Select the item “Alignment” within the Setting menu (see § 5.2.1).
2. Use the key
and then the keys or to set the value of the distance of the lens
from the object. The following values are available: 0.5m, 1m, 1.5m and >2m
3. Press the key “Select” to confirm or “Close” to exit without saving.
