Operation
Inserting the batteries
• Insert the supplied battery before first use.
Caution!
Make sure that the surface of the device is dry and the
device is switched off.
1. Open the cover of the battery compartment.
2. Use the battery clip to connect the new battery with correct
polarity.
3. Insert the battery in the battery compartment.
4. Close the cover of the battery compartment.
Carrying out a measurement
Note:
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 10:1 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.
Note:
The first object at which you point the device and the
temperature of which you measure is then also the reference
value for all further measurements. The reference value is
indicated on the reference value display.
1. Point the device at the object to be measured.
2. Press the measurement button(5).
ð The reference value is indicated on the reference value
display(20).
ð The SCAN indication(19) appears on the display.
ð The current measured value is displayed in the
measurement value display(17).
3. Press the measurement button(5) again if you want to
"freeze" a measured value.
ð The current measured value will be halted.
ð The HOLD indication(18) appears on the display.
Carrying out a measurement with threshold values
The device permits you to set a threshold value relating to the
set reference temperature. Exceeding or falling below the
reference temperature by more than this selected threshold is
indicated visually and acoustically.
To determine the threshold value relating to the reference
temperature use the selector switch(1) at the side of the device.
The following settings are available:
• OFF: The threshold is disabled.
• 1°C: The threshold value is respectively 1°C (1.8°F)
higher or lower than the reference value.
• 3°C: The threshold value is respectively 3°C (5.4°F)
higher or lower than the reference value.
• 5°C: The threshold value is respectively 5°C (9°F) higher
or lower than the reference value.
The selected threshold is indicated on the respective
display(15).
If the current measured value exceeds the set reference value
by the selected threshold, the LED will be illuminated in red and
an acoustic signal can be heard at frequent intervals.
If the current measured value is within the set range given by
the threshold values, the LED is illuminated in green.
If the current measured value falls below the set reference value
by the selected threshold, the LED will be illuminated in blue
and an acoustic signal can be heard at long intervals.
