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 the symbol with the utmost attention.
The following symbol is used in this manual:
CAUTION
When this symbol is displayed, the instrument is able to emit a laser pointer.
Always prevent the laser from radiating your eyes, in order to avoid any
injury. Class 2 laser device according to EN 60825-1.
1.1. PRELIMINARY INSTRUCTIONS CAUTION
Use the instrument only as specified in this user manual. Improper use may
damage the instrument.
During use and storage, keep the instrument away from direct sunlight or
sources of light, hot surfaces or objects, high temperatures, high humidity
or particularly critical environmental conditions.
After a period of storage under extreme environmental conditions, let the
instrument resume normal operating conditions before using it.
Moving the thermometer quickly from a cold to a warm place it may
condense on the focal lens from which infrared radiation is captured. Wait
until condensation is absorbed before taking measurements.
Do not touch the internal focal lens.
Make sure that the target is larger than the unit's spot size. The smaller the
target, the closer you should be to it. When accuracy is critical, make sure
the target is at least twice as large as the spot size.
Do not carry out measurements under conditions exceeding the limits
specified in § 7.
Make sure that battery is correctly installed.
Do not carry out any measurement if you notice anomalous conditions such
as breakages, leakages of battery liquid, blind display, etc.
This instrument is not recommended for use in measuring shiny or polished
surfaces (stainless steel, aluminum, etc.).
The instrument cannot measure temperature through transparent surfaces
such as glass. The instrument will measure the surface temperature of the
glass instead.
Steam, dust, smoke, etc. can prevent accurate measurements.

1.2. DURING USE
Please carefully read the following recommendations and instructions:
CAUTION
Never press the trigger Twhen symbol is displayed and the instrument
is directed towards the eyes. The instrument emits a laser pointer.
If the target has a smooth surface reflecting the laser, prevent the laser from
beaming your eyes.
Never radiate the laser if flammable gas is present.
If symbol “ ”is displayed during use, interrupt testing and replace the
batteries according to the procedure described in § 6.2
Be extremely careful when the laser pointer is turned on.
Do not direct the instrument, especially the laser beam, towards people or
animals.
When using the laser pointer, be careful no to direct the beam onto a
reflective surface which could reflect the beam into your eyes.
Never radiate the laser if flammable gas is present.
1.3. AFTER USE
If the instrument is not to be used for a long time, 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. However, we suggest you to check it rapidly, to detect possible damage
which may have occurred during transport. In case you find out anomalies, immediately
contact the Dealer. We also recommend checking that the packaging contains all
components indicated in § 7.4. In case the instrument should be returned, please follow
the instructions given in § 8.1.

batteries, see § 6.2
3.3. CALIBRATION
The instrument has the technical specifications described in this manual. Its performance
is guaranteed for one year starting from the date of purchase.
3.4. STORAGE
In order to guarantee precise measurements, after a long storage time under extreme

4.3. DESCRIPTION OF FUNCTION KEYS
4.3.1. Trigger key T
The Trigger key T (see Fig. 1 – part 6) allows the following operations:
Switching on the instrument and activating measurement by continuously pressing
(“SCAN” symbol on display)
Automatic switching of the HOLD mode (data fixed on display) when releasing after
measurement
4.3.2. key
The key allows the activation/deactivation of the double laser pointer by pressing trigger
key T. The “ ” symbol (see Fig. 3 – part 3) is displayed
4.3.3. °C/°F/ key
Simply pressing °C/°F/ key allows activation/deactivation of the acoustic buzzer (see Fig.
4 – part 4) associated to MAX and MIN measurements performed by the instrument by
pressing trigger T key
Long pressing of °C/°F/ key allows selection of “°C” (Celsius) or “°F” (Fahrenheit) units
4.3.4. MAX/MIN key
Pressing MAX/MIN key allows selection of Maximum value (“MAX” symbol on display) or
Minimum value (“MIN” symbol on display) in the secondary display (see Fig. 3 –part 7) by
pressing trigger T key

5. OPERATING INSTRUCTIONS
5.1. TEMPERATURE MEASUREMENT
1. Switch on the instrument by pressing trigger key T
2. Press key to activate/deactivate the double laser pointer (see § 4.3.2)
3. Press °C/°F/ to activate/deactivate the acoustic buzzer in the MAX or MIN
measurements (see § 4.3.3)
4. Press and hold Trigger key Tto activate the test and point the instrument in the
direction of the target ‘s surface
CAUTION
The instruments allows correct temperature measurement only on materials
with emissivity value equal or higher than 0.95 (not-reflecting object with
oxidized surfaces)
The double laser beam allows an immediate evaluation of the maximum
size of the measuring spot with regard to the distance from the target in
order to get a correct temperature measurement.
5. Make sure that the target, whose temperature is to be measured, is at least as large as
the unit’s spot (see Fig. 4). The smaller the object is, the closer you should be to it
(Example: if the distance from the object is 300mm – 12inch, the section of the object
should be at least of 25mm – 1inch for a correct temperature measurement). When
accuracy is critical, make sure the object is at least twice as large as the spot
size

6. Release Trigger key T to stop measuring and freeze the last read value on the main
display. The message “HOLD” is shown. The MAX or MIN value is also shown on the
secondary display
7. The instrument will automatically switch off after 10 seconds of idleness.
