of these instructions. Likewise, we take no responsibility for any incorrect
readings and for any consequences which may result from them.
• Please take particular note of the safety advice!
• Please keep this instruction manual for future reference.
2. Field of operation and all the benefits of your new instrument at a glance
• For contact-free measuring of surface temperature even of hot, hazardous, or
hard-to-reach objects.
3. For your safety
• This product is exclusively intended for the field of application described above.
It should only be used as described within these instructions.
• Unauthorized repairs, modifications or changes to the product are prohibited
and might result in dangerous laser radiation.
• The product is not recommended for taking body temperature.
Caution!
Risk of injury
• The product is equipped with a class 2M laser. If the sign on the device is not
written in the language of your country, please affix the sign below onto the
device.
ATTENTION – LASER CLASS 2M
Never look directly into the laser beam.
Do not direct the laser beam into the eyes of a person or animal.
It can cause permanent damage to the eye.
Wavelength: 635 - 660 nm / Output: <1mW
• Do not point the laser beam at mirrors or other reflective surfaces. The uncon-
trolled reflected beam may strike people or animals.
• Do not aim too close at hot or dangerous targets.
• Keep this instrument and the batteries out of the reach of children.
• Batteries contain harmful acids and may be hazardous if swallowed. If a battery
is swallowed, this can lead to serious internal burns and death within two
hours. If you suspect a battery could have been swallowed or otherwise caught
in the body, seek medical help immediately.
• Batteries must not be thrown into a fire, short-circuited, taken apart or
recharged. Risk of explosion!
• Never use a combination of old and new batteries together, nor batteries of dif-
ferent types.
• Low batteries should be changed as soon as possible to prevent damage
caused by leaking.

• Wear chemical-resistant protective gloves and safety glasses when handling
leaking batteries.
Important information on product safety!
• Do not place your product near extreme temperatures, vibrations or shocks.
• Protect the unit from large or abrupt ambient temperature changes.
• Do not leave the unit near objects of high temperature.
• Do not immerse the unit in water. Water can penetrate and cause malfunction.
Protect it from moisture.
• Check the housing before using the device. Do not use the device if it seems to
be damaged. Check for cracks or missing plastic parts.
• Steam, dust, smoke, etc., can prevent accurate measurement by obstructing the
unit's optics.
EMC/RFI
• Protect the unit from EMI (Electro Magnetic Interference) from induction
heaters and microwave ovens and Electro Static Discharge. Readings may be
affected if the unit is operated within a radio frequency electromagnetic field
strength of approximately 3 volts per meter, but the performance of the instru-
ment will not be permanently affected.
4. Use
• Press and hold the measuring button to activate the measuring process.
• The backlight is automatically activated.
• The circular laser allows you to target the center of the area to be measured.
• Release the measuring button.
• On the display appear HOLD and the latest measured temperature for about 15
seconds.
• The maximum value (MAX appears on the display) will be displayed during the
measurement.
• Press the °C/°F button and you can change between Celsius (°C) or Fahrenheit
(°F) as temperature unit.
• When the instrument is not used, it will automatically switch off after 15 sec-
onds.
5. Distance, Spot Size, and Field of View
• As the distance (D) from the object increases, the spot size (S) of the area
measured by the unit becomes larger a ratio D:S = 12:1 (e.g. 120 cm distance =
10 cm spot size). To get the most accurate temperature reading, aim at the tar-
get as near as possible.
• Should the distance be too great, there is a risk that the temperature has also
been taken outside the aimed target.
• The circular laser helps to aim at the exact area to be measured. The laser circle
and the measuring spot are congruent at a distance of 2 m.
Please take note of the following:
• Not recommended for use in measuring shiny or polished metal surfaces
(stainless steel, aluminum, etc.).
• The unit cannot measure through transparent surfaces such as glass or plastic.
It will measure the surface temperature of the glass instead.
