• 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!
• Low batteries should be changed as soon as possible to pre-
vent damage caused by leaking.
• Make sure the polarities are correct.
• Avoid contact with skin, eyes and mucous membranes when
handling leaking batteries. In case of contact, immediately
rinse the affected areas with water and consult a doctor.
Important information on product safety!
• Do not expose the device to extreme temperatures, vibra-
tions or shocks.
• Protect the unit from large or abrupt temperature changes.
• Do not leave the unit near objects of high temperature.
• Do not immerse the unit into water. Water can penetrate and
cause malfunction. Protect from moisture.
• Steam, dust, smoke, etc., can prevent accurate measure-
ment by obstructing the unit's optics.
• Protect the instrument from EMI (Electro Magnetic Interfer-
ence) from induction heaters and microwave ovens and
Electro Static Discharge
4. Use
Just aim at the measuring object and press the button.
• Read the surface temperature in less than one second. When
the button is released, the last temperature reading will hold
on the display for 15 seconds.
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 = 1:1 (e.g. 10 cm distance = 10 cm spot size).

• To get the most accurate temperature reading, aim at the
target as near as possible.
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.
