many measured values fall above a cer-
tain temperature threshold. If very small
but hot objects are being measured, it
may select the low temperature range
that is not suitable for high tempera-
tures. This can be determined from the
preceding symbol, ~. In such cases,
switch to the <Manual> measuring func-
tion, in which the color distribution cor-
responds to the set temperature range.
<Heat Detector> – Only the warmer
temperatures in the measuring range
are displayed as a thermal image in this
measuring function. The area outside
these warmer temperatures is shown as
a real image in grey scale. The depiction
in grey scale prevents colored objects
from being wrongly associated with tem-
peratures (e.g. a red cable in the control
cabinet when searching for overheated
components). Adjust the scale using
the Up Arrow Button 8 and Down Arrow
Button 13. This expands or reduces
the temperature range, thereby expand-
ing or reducing the thermal image. The
measuring tool continues to measure
minimum and maximum temperatures
and displays these at the ends of the
Color Scale 36.
<Cold Detector> – Only the colder
temperatures in the measuring range
are displayed as a thermal image in this
measuring function. The area outside
these colder temperatures is shown as
a real image in grey scale to prevent
colored objects from being wrongly
associated with temperatures (e.g. a
blue window frame when searching for
faulty insulation). Adjust the scale using
the Up Arrow Button 8 and Down Arrow
Button 13. This expands or reduces
the temperature range, thereby expand-
ing or reducing the thermal image. The
measuring tool continues to measure
minimum and maximum temperatures
and displays these at the ends of the
Color Scale 36.
<Manual> – If greatly deviating tempera-
tures are measured in the thermal image
(e.g. a radiator as a hot object when
searching for thermal bridges), the
available colors are distributed among
a large number of temperature values
in the range between the maximum
and the minimum temperature. This
Functions
can result in a situation where subtle
temperature differences can no longer
be shown in detail. To obtain a detailed
depiction of the temperature range to
be examined, take the following steps:
After switching to <Manual> mode, you
can set the maximum and the minimum
temperature. Doing this enables you to
set the temperature range that is rele-
vant to you and in which you would like
to detect subtle differences. The <Reset
scale> setting automatically readjusts
the scale to the measured values in the
infrared sensor's field of view.

• <Emissivity> 32 – A selection of saved
emissivities is available for some of the
most common materials. Choose the
relevant material in the <Material> menu
item. The corresponding emissivity is
shown in the line beneath. If you know
the exact emissivity of the object you
want to measure, you can also set it as
a numerical value in the <Emissivity>
menu item.
If you frequently measure the same
materials, you can enter five emissivities
as favorites and quickly call them up via
the bar at the top (numbered from 1 to
5).
• <Reflected Temp.> 31 – Setting this pa-
rameter can improve the accuracy of the
measuring result, especially with low-
emissivity (= high-reflection) materials.
In some situations (especially in indoor
areas) the reflected temperature cor-
responds to the ambient temperature. If
there are objects with greatly deviating
temperatures close to highly reflective
objects, this value should be adjusted
as the measurement may be affected.
