Emissivity
You can choose between user-defined emissivity and 8 materials
with set emissivity. The reflected temperature (RTC) can be set
individually.
Emissivity information:
The emissivity describes the capability of a body to emit
electromagnetic radiation. This is material-specific and must be
adapted for correct measurement results.
Non-metals (paper, ceramic, gypsum, wood, paints and coatings),
plastics and food have high emissivity, which means that thesurface temperature can be easily measured using infrared.
Because of their low or non-uniform emissivity, bright metals andmetal oxides only have limited suitability for infrared measurement.
Highly inaccurate measurements should be expected. A remedy forthis is coatings that increase emissivity, e.g. paint or emission
adhesive (accessory, 0554 0051), which must be applied to theobject to be measured.
The following table gives typical emissivities of important materials.
These values can be used as a guide for user-defined settings.

Reflected temperature information:
Using this offset factor, the reflection is calculated out based on the
low emissivity, and the accuracy of the temperature measurementwith infrared instruments is improved. In most cases, the reflected
temperature is identical to the ambient air temperature. Only when
objects with strong emissions and much higher temperatures (suchas ovens or machines) are in proximity to the object being
measured should the radiation temperature of theses heat sources
be determined and used (e.g. using a globe thermometer). The
reflected temperature has little effect on objects with highemissivity.
Using the PC software, other materials can be imported into
the instrument from an existing list.

Histogram adjustment
By adjusting the colour palette to the current temperature
distribution, histogram adjustment particularly in the case of scenes
with a large temperature scope (e.g. with high-temperature
measurements) increases the contrast.
When histogram adjustment is activated, the colours within
the scale are no longer distributed in a linear pattern
between the minimum and maximum scale value. It istherefore difficult to draw conclusions about temperaturesfrom colours.

Before calling up the function, please note:
When the function is called up, the scale is set to manual and thetemperature scope at this time is fixed. This temperature scope
may not be sufficient for the entire panoramic image.
Recommendation:> Scan the entire object for the panoramic image to determine therequired temperature scope (minimum/maximum measurement
value). Set scale to manual and set scale limits, see Scalemanual, page 45.
If the SuperResolution function is activated, it is deactivated when
the image stitching wizard is called up. When the image stitching
wizard is ended, SuperResolution is activated again.

Generally, the grey palette is automatically activated in the
FeverDetection menu. There is also a range selection visible inthe centre of the live thermal image. The hotspot is automaticallyshown within this range selection.
The FeverDetection assistant detects a person's warmest pointand compares it with a progressive mean value of previous
persons.
56

6 Using the productIn the event of a deviation (the deviation difference can be
manually adjusted under the Tolerance menu item) from this meanvalue, the thermal imager triggers an acoustic and visual alarm.
The progressive mean value can be calculated in two different
modes:
Manual mode
The person’s reading is included in the mean value once this has
been confirmed manually by pressing a button.
Automatic mode
The thermal imager detects a person via the built-in facialrecognition. As soon as the thermal imager has detected theperson, the reading is determined and included in the mean value
calculation.
The thermal imager’s recorded temperatures are lower thanthe person's true body temperature, since the thermal
imager can only measure the temperatures on the surface.
The thermal imager cannot be used to diagnose fever. It
compares the surface temperature of different people andgives an indication as to whether a person may have an
elevated body temperature.
The FeverDetection menu includes the following submenu items:

Radio
This function is not available in all countries.
A radio humidity probe can be logged onto the instrument.
Every radio probe has a probe identification number (RFID). This is
made up of the three-digit RFID number on the probe and theposition of the switch in the battery compartment of the radio probe(H or L). To be logged on at the instrument, the radio probe must
be switched on and the transfer rate must be set to 0.5 s. This isdone by briefly pressing the on/off button when switching on (alsosee instructions for use of radio probe).
If no radio probe is found, this may be because of the following:• The radio probe is not switched on or the radio probe battery is
dead.
• The radio probe is outside the radio range.
• Sources of interference influence radio transmission (e.g.
reinforced concrete, metal objects, walls or other barriers
between the transmitter and receiver, other transmitters of thesame frequency and strong electromagnetic fields).
> If necessary: Rectify the possible causes of the fault in radiotransmission.

Important framework conditions
Please observe the following framework conditions in order toobtain significant measurement results.
Humidity measurement:• Pivot the separate humidity measuring instrument or optional
radio humidity probe slightly to shorten the adjustment time.
Avoid sources of interference (e.g. exhaled air).
Building thermography, investigating the building shell:• Considerable temperature difference between inside andoutside required (ideal: >15°C / >27°F).
• Consistent weather conditions, no intensive sunlight, no
precipitation, no strong wind.
To ensure maximum accuracy, the imager requires an adjustment
time of 10 minutes after it is switched on.
When using the super-telephoto lens, if there is a change
in the ambient conditions the camera may require an
adjustment time of > 10 min.
Important settings
Before recording an image, check whether the protection glass
option is set correctly to prevent corruption of the measurement
results, see Optics, page 65.
Before saving an image, make sure that it is correctly focussed,manually (see Manually focusing the image, page 30) or
automatically (see Automatically focusing the image, page 31).
Images that are not in focus cannot be corrected retroactively!
To obtain precise measurement values, the emissivity and reflected
temperature must be set correctly, see Emissivity, page 43.
Subsequent adjustment is possible via the PC software, if required.
When humidity is high or the imager is a considerable distancefrom the object to be measured, atmospheric correction increases
measurement accuracy, see Atmospheric correction, page 42.
When auto-scaling is activated, the colour scale is continuously
adjusted to the min.-/max.- values of the current measurement
image. This means that the colour assigned to a specifictemperature is changing constantly! To be able to compare multiple
images based on the assigned colour, scaling must be set
manually to fixed values (see Scale manual, page 45), or must be
subsequently adjusted to uniform values using the PC software.
