1 PRECAUTIONS AND SAFETY MEASURES
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 symbol with the utmost attention.
Before and after carrying out the measurements, carefully observe the following instructions:
CAUTION
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 use the instrument in environments with temperatures exceeding the
operating and storage limits specified in § 3.1.1 in order not to damage it
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.
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.
Use 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.
CAUTION
Please read the instruction manual of the instrument which is included on CD-ROM
support, before use

2.2 DESCRIPTION OF FUNCTION KEYS
The instrument has 8 function keys described further in this text and a trigger key “T” with multiple functions.
2.2.1 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. 4 – 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. 4 – middle).
3. After a few seconds, the IR image is shown on the display and the instrument is ready for measurement
(see Fig. 4 – right side).
Fig. 4: 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.
2.2.2 Switching off the instrument
1. Press and hold key for at least 4s to switch off the instrument. The following screen appears on
the display
Fig. 5: Switching off the instrument
2. Touch the virtual button “OK” to switch off the instrument.
3. Touch the virtual button “Cancel” to cancel the operation and go back to normal display.
4. By pressing and holding the key for at least 7s, the instrument is directly switched off
2.2.3 Key
Press and hold key for 2s to switch on/off the instrument's laser pointer. The symbol “ ” is found in
the top part of the display. The same key is also used for measuring the distance between the instrument
and the framed target.

2.2.4 Key
Press key to enter the gallery of images/videos saved in the internal memory or on the inserted micro SD
card.
2.2.5 T key (Trigger)
Pressing the Tkey found on the front part of the instrument allows freezing the IR image on the display and
automatically opens the section for saving the image. Press the Tkey again to unfreeze the image on the
display.
2.2.6 Key Menu/OK
Pressing the key Menu/OK allows displaying/hiding the instrument's main menu. The operation is always
possible also by touching the display.
2.2.7 Key
Long pressing key allows switching on/off the instrument. With the instrument switched on, by pressing
key several times, it is possible to select the image temperature adjusting modes.
