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 degree of emission.
•
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.
1. Point the device at the object to be measured.
2. Press the measurement button (6).
ð
Hold onto the measurement button (6) if you want to
perform a prolonged measurement.
ð
The device turns on and carries out a measurement.
The SCAN indication (17) appears on the display.
ð
The current measured value is displayed in the
measurement value display (16).
3. Let go of the measurement button (6) again.
ð
The device stops measuring. HOLD (18) appears on the
display. Depending on the setting of the device, either
the maximum or minimum value of the last
measurement cycle will be shown in addition.
ð
The device switches off after approx. 8 seconds.
