Carrying out a measurement
Info
Please note that moving from a cold area to a warm
area can lead to condensation forming on the device's
circuit board. This physical and unavoidable effect can
falsify the measurement. In this case, the display
shows either no measured values or they are incorrect.
Wait a few minutes until the device has become
adjusted to the changed conditions before carrying out
a measurement.
• Ensure that the surface to be measured is free of dust, dirt
or similar substances.
• To be able to gain exact measurement results on surfaces
which reflect heavily, stick matt masking tape to the
surface or apply matt black paint with a very high and
known emissivity.
• Note the 12:1 ratio of the distance to the measuring spot
size. For accurate measurements the measuring object
should be at least twice as large as the measuring spot.
Please proceed as follows to carry out a measurement:
1. Point the device at the object to be measured.
2. Press the Measurementbutton(3).
ð Hold onto the Measurementbutton if you want to
perform a prolonged measurement.
ð The device turns on and carries out a measurement.

Warning of laser radiation
Class 2 laser radiation.
Lasers of class 2 only radiate in the visible range and
during continuous wave operation (lasting beam) no
more than 1 milliwatt (mW) of output will be emitted.
Looking directly into the laser beam for a longer period
of time (more than 0.25seconds) can cause damage to
the retina.
Avoid looking directly into the laser beam. Never look
into the laser beam using optical aides. Do not
suppress the winking reflex when looking into the laser
beam unintentionally. Never point the laser beam at
people or animals.
