Note
• A thermal camera measures surface temperatures. The camera cannot measure core
body temperature or diagnose a fever.
• For accurate temperature measurements, it is very important to adjust focus correctly.
14.1.4.1
Measurement parameters
The measurement parameters are important for accurate measurements. In Screening
mode, the camera automatically sets the appropriate parameters.
There is typically no need to change the default measurement parameters, see table
below.
Object distance
1.0 m (3.3 ft.)
Atmospheric temperature
20°C (69°F)
Relative humidity
50%
Reflected temperature
20°C (69°F)
Emissivity
0.95

Color alarms
By using color alarms, anomalies can easily be discovered in an infrared image. The col-
or alarm applies a contrasting color to all pixels with a temperature above, below, or be-
tween the set temperature levels. The color alarms are available on the
Color
menu.
14.1.6
Non-uniformity correction (NUC)
When the thermal camera displays
Calibrating...
it is performing what in thermography is
called a ”non-uniformity correction” (NUC).
An NUC is performed automatically, for example at start-up or when the environment
temperature changes.
It is also possible to perform an NUC manually, by pushing and holding down the image
archive button
for more than 2 seconds.

Saving images and video
14.2.1
General
When you save an image or record a video clip, the camera stores the image or video file
on the memory card.
For instructions on how to insert the memory card, see section .
Note
Empty or use a memory card that has not previously been used in another type of
camera. The cameras may organize files differently on the memory card. There is there-
fore a risk of losing data if the same memory card is used in different types of cameras.
14.2.2
Saving an image
To save an image, pull the trigger.
