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 target as near as possible.
• Should the distance be too great, there is a risk that the temperature has also been taken out-
side the aimed target.
Please take note of the following:
• Not recommended for use in measuring shiny or polished metal surfaces (stainless steel,
aluminium, etc.).
• The unit cannot measure through transparent surfaces such as glass or plastic. It will meas-
ure the surface temperature of the glass instead.
6. Care, maintenance, battery replacement
• The sensor lens is the most delicate part of the thermometer. Please protect the sensor part
from dirt.
• Clean your instrument with a soft damp cloth. Do not use solvents or scouring agents.
• Remove the batteries if you do not use the product for a long period of time.
• Change the batteries, when the battery symbol appears on the display.
• Confirm the device is power off before changing the batteries.
