Temperature measurements will only be correct if the emissivity setting
u
matches the emissivity of the object. Otherwise, object temperatures could be
shown to be hotter or colder than they are, which may present a danger if touched.
Measuring surface for surface temperature measurements
The laser circle produced by the measuring tool indicates the measuring surface. The in-
frared radiation of this measuring surface is then determined when performing a contact-
less surface temperature measurement.
The central laser point marks the centre of the measuring surface. For an optimum meas-
urement reading, position the measuring tool so that the laser beam meets the measur-
ing surface perpendicularly to this point.
Do not direct the laser beam at persons or animals and do not stare into the laser
u
beam yourself (even from a distance).
Increasing the distance between the measuring tool and the object being measured in-
creases the size of the laser circle and therefore the size of the area being measured. The
optimum measuring distance is 0.75 m to 1.25 m.
Do not hold the measuring tool directly against hot surfaces. The heat can damage
u
the measuring tool.
The displayed reading is the average value of all temperatures measured within the
measuring surface.
Information about the measuring conditions
Highly reflective, shiny or transparent surfaces (e.g. high-gloss tiles, stainless steel cup-
board fronts or saucepans) may impair the surface temperature reading. If necessary,
mask the area to be measured with a dark, matt adhesive tape that conducts heat well.
Allow the tape to acclimatise briefly on the surface.
It is not technically possible to perform measurements through transparent materials.
