Infrared thermal radiation
Infrared thermal radiation is electromagnetic radiation emit-
ted by every body above 0 Kelvin (−273 °C). The amount of
radiation depends on the temperature and the emissivity of
the body.
Emissivity
The emissivity of an object depends on the material and the
structure of its surface. This specifies how much infrared
thermal radiation the object emits compared with an ideal
radiant warmer (black body, emissivity ε = 1) and accord-
ingly has a value between 0 and 1.
Thermal bridge
A thermal bridge is defined as a position on the external wall
of a building, where there is a localised increase in heat loss
due to a structural defect.
Thermal bridges can lead to an increased risk of mould.
Reflected Temperature/Reflectivity of an Object
The reflected temperature is the thermal radiation that is not
emitted by the object itself. Depending on the structure and
material, background radiation is reflected in the object to
be measured, therefore distorting the actual temperature
result.
Distance from the Object
The distance between the object being measured and the
measuring tool influences the captured area size per pixel.
You can capture increasingly large objects as the distance
from the object becomes greater.

Maintenance and Service
Maintenance and Cleaning
Only store and transport the measuring tool in a suitable
container, such as the original packaging.
Keep the measuring tool clean at all times. A dirty infrared
sensor (23) may impair the measuring accuracy.
When cleaning the measuring tool, ensure that no liquids
enter the tool.
Do not attempt to remove dirt from the infrared sensor (23),
camera (24), speaker (18) or microphone (15) using sharp
objects. Do not wipe over the infrared sensor and camera
(risk of scratching).

Please contact an authorised Bosch after-sales service
centre if you want to have your measuring tool recalibrated.
If repairs are required, send in the measuring tool in its ori-
ginal packaging.
There are no parts which can be serviced by the user on the
measuring tool. Opening the housing shell can destroy the
measuring tool.
Changing the Button Cell (see figure B)
Unscrew the screw (4) on the button cell holder. Pull the
button cell holder (2) out of the measuring tool with an auxil-
iary tool (e.g. a flat-head screwdriver). Change the button
cell. Retighten the screw (4) after inserting the button cell
holder.

The contained lithium-ion batteries are subject to the Dan-
gerous Goods Legislation requirements. The batteries are
suitable for road-transport by the user without further re-
strictions.
When shipping by third parties (e.g.: by air transport or for-
warding agency), special requirements on packaging and la-
belling must be observed. For preparation of the item being
shipped, consulting an expert for hazardous material is re-
quired.
Dispatch battery packs only when the housing is undam-
aged. Tape or mask off open contacts and pack up the bat-
tery in such a manner that it cannot move around in the
packaging. Please also observe the possibility of more de-
tailed national regulations.
