• Protect the measuring tool against
moisture and direct sun light.
• Do not subject the measuring tool to
extreme temperatures or variations in
temperature. As an example, do not
leave it in vehicles for a long time. In
case of large variations in temperature,
allow the measuring tool to adjust to
the ambient temperature before putting
it into operation. In case of extreme
temperatures or variations in tempera-
ture, the accuracy of the measuring tool
can be impaired.
• Make sure that the tool is correctly
acclimatized. In the event of severe tem-
perature fluctuations or environmental
conditions which vary to a large degree,
the measurement accuracy of the mea-
suring tool may be impaired until it is
fully acclimatized again.
• Avoid hard knocks to the tool or drop-
ping it. After severe external influences
and in the event of abnormalities in the
functionality, you should have the mea-
suring tool checked by an authorized
Bosch after-sales service agent.

Operation
Initial Operation
Switching On and Off
To take a measurement, fold the Protective
Cap 1 upwards. Make sure that the infrared
measuring area is not closed off or covered
while working.
To switch on the tool, press the On/Off But-
ton 12. A start sequence will appear in the
Display 18. After the start sequence, the
measuring tool will immediately begin to
measure and will measure continuously until
it is switched off.
Note: In the first few minutes, the measur-
ing tool may self-calibrate several times, as
the sensor temperature and ambient tem-
perature have not yet been brought into line.
Performing calibration again enables precise
measurement. The thermal image freezes
briefly during calibration.
During this time, the temperature indicator
may show ~. The thermal image will freeze
briefly during sensor calibration. If the ambi-
ent temperature fluctuates significantly, this
effect is increased. If possible, you should
therefore turn on the measuring tool a few
minutes before starting to measure, so that
the tool can stabilise thermally.
