1 PRECAUTIONS AND SAFETY MEASURES
In the whole manual, the word “instrument” generically indicates models THT60 and
THT70, 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:
CAUTION
xDo not carry out any measurements in case gas, explosive materials or
flammables are present, or in humid or dusty environments.
xDo 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.
xKeep the instrument steady during any measuring operation.
xDo not carry out any measurements which exceed the working and storage
temperature ranges specified in § 8.1.1.
xOnly 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.
xCheck that the battery is correctly inserted.
xCheck that the LCD display gives indications consistent with the function
selected.
xDo not direct the instrument at very high intensity radiation sources (e.g. the
sun) in order to prevent damaging the IR sensor.
xPrevent hits or strong vibrations in order to keep the instrument from
damage.
xWhen bringing the instrument from a cold to a hot environment, leave it on
long enough for condensation water to evaporate.
xOnly use the micro SD card provided with the instrument.
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.
Compliant with European Standards
1.1 DURING USE
CAUTION
xFailure 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.
xUse the instrument only in the temperature ranges indicated in this manual.
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 § 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).
