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.

Corrective measure
Allow the measuring tool to reach the correct temperature.
Transfer the images to another storage medium (e.g. com-
puter) when necessary. Then delete the images in the internal
memory.
Format the internal memory by deleting all images. If the
problem persists, send the measuring tool to an authorised
Bosch after-sales service centre.
Send the measuring tool to an authorised Bosch after-sales
service centre.
Check whether the driver on your computer is up to date. It
may be necessary to have a newer operating system version
on your computer.
Check whether the measuring tool can be connected to a dif-
ferent computer. If not, send the measuring tool to an author-
ised Bosch after-sales service centre.

Maintenance and Service

Maintenance and Cleaning

Only store and transport the measuring tool in a suitable
container, such as the original packaging. Do not affix any
stickers near to the sensor on the measuring tool.
Keep the measuring tool clean at all times. A dirty infrared
sensor (16) 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 (16)
or camera (15) using sharp objects. Do not wipe over the in-
frared 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.
The integrated button cell may only be removed for disposal
by qualified personnel.
There are no parts which can be serviced by the user on the
measuring tool. Opening the housing shell can destroy the
measuring tool.
