exact emissivity of the object you want to measure,
you can also set it as a numerical value in the
<Emissivity> menu item.
▪ <Reflected temp.> (b)
Setting this parameter can improve the accuracy of the
measuring result, especially with low-emissivity
(= high-reflection) materials. In some situations (espe-
cially in indoor areas) the reflected temperature cor-
responds to the ambient temperature. If there are ob-
jects with greatly deviating temperatures close to
highly reflective objects, this value should be adjusted
as the measurement may be affected.
– <Display>
▪ <Centerspot> (k)
The point is displayed in the centre of the thermal im-
age and shows you the measured temperature value at
this point.
▪ <Hotspot> (j): <ON>/<OFF>
The hottest point (= measuring pixel) is indicated by
red crosshairs in the thermal image. This facilitates the
search for critical areas (e.g. a loose contact terminal
in the control cabinet).
▪ <Coldspot> (l): <ON>/<OFF>
The coldest point (= measuring pixel) is indicated by
blue crosshairs in the thermal image. This facilitates
the search for critical areas (e.g. a leak in a window).
▪ <Color scale> (g): <ON>/<OFF>
– <WiFi> (d): <ON>/<OFF>

Documenting Measurements
Saving Measurements
The measuring tool begins to take measurements as soon as
it is switched on and does so continuously until it is switched
off.
To save an image, point the camera at the required measur-
ing object and press the "Save" button (11). The image is
saved in the internal memory of the measuring tool. Alternat-
ively, press the measuring button (17) (pause). The meas-
urement is frozen and shown in the display. This enables you
to carefully view the image and to make retrospective adjust-
ments (e.g. to the colour palette). If you do not wish to save
the frozen image, restart measuring mode by pressing the
measuring button (17). If you wish to save the image in the
internal memory of the measuring tool, press the "Save"
button (11).
Calling Up Saved Images
Proceed as follows to call up saved thermal images:
– Press the left-hand function button (13). The most re-
cently saved photo now appears in the display.
– Press the right-hand (8) or left-hand (12) arrow button to
switch between the saved thermal images.
You can also display the thermal image taken as a full-screen
image by pressing on the up arrow button (5).
Deleting saved images
Change to the gallery view to delete individual thermal im-
ages:
– Press the right-hand function button (7) under the waste
paper basket symbol.
– Confirm the process by pressing the left-hand function
button (13) or cancel the deletion by pressing the right-
hand function button (7).
<Delete All Images>
In the <Delete All Images> menu, you can delete all the files
in the internal memory at the same time. Press the Func (6)
button to call up the measuring functions. Now press the
right-hand function button (7) and select <Tool> → <Delete
All Images>. Press the right-hand arrow button (8) to enter
this submenu. Then press either the left-hand function
button (13) to delete all files, or the right-hand function
button (7) to cancel.
