6. 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 at a
ratio D:S = 9:1 (e.g. 90 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 the temper-
ature outside the aimed target has also been taken. The cir-
cular laser helps to aim at the exact area to be measured.
Please take note of the following
• Not suitable for measuring shiny or polished metal surfaces
(stainless steel, aluminium, etc.).
• The unit cannot measure through transparent surfaces such
as glass or plastic. It will measure the surface temperature
of the glass instead.
7. Care and maintenance
• The sensor lens is the most delicate part of the thermome-
ter. Please protect it from dirt.
• Clean your instrument with a soft damp cloth. Do not use
solvents or scouring agents.
• Remove the battery if you do not use the product for a long
period of time.
7.1 Battery replacement
