This can result in a situation where subtle temperature
differences can no longer be shown in detail. To obtain a
detailed depiction of the focus temperature, switch to
"Manual" mode and set the maximum and the minimum
temperature. Doing this enables you to set the tempera-
ture range that is relevant to you and in which you would
like to detect subtle differences. The Reset setting auto-
matically readjusts the scale to the measured values in the
infrared sensor's field of view.
Main Menu
To access the main menu, press the "Func" button 6 to call up
the measuring functions. Now press the right-hand function
button 7.
– "Measurement"
– "Emissivity" c:
A selection of saved emissivity levels is available for
some of the most common materials. Select the appro-
priate material in the "Material" menu item. The corre-
sponding emissivity is displayed in the line below.
If you know the exact emissivity of the object to be meas-
ured, you can also set it as a numerical value in the
"Emissivity" menu item.
– "Reflected temperature":
Setting this parameter improves the accuracy of meas-
uring results, especially with low-emissivity (= high-re-
flection) materials. The reflected temperature normally
corresponds to the ambient temperature.
If there are objects with greatly deviating temperatures
close to highly reflective objects which could affect the
measurement, this value should be adjusted.
– "Display"
– "Hotspot" k: "ON/OFF"
–
In this function, the hottest point (= measuring pixel) in
the measurement range is automatically highlighted by
red crosshairs in the thermal image. This can help you to
detect a critical point, e.g. to locate a loose terminal in
the control cabinet.
– "Cold spot" m: "ON/OFF"
The coldest point (= measuring pixel) in the measure-
ment range is automatically highlighted by blue cross-
hairs in the thermal image. This can help you to detect a
critical point, e.g. to locate a leak in insulation.
– "Crosshairs" l: "ON/OFF"
The crosshairs are displayed in the centre of the thermal
image and show you the measured temperature value at
this point.
– "Scale" h: "ON/OFF"
– "WLAN": "ON/OFF"
(see "Data Transmission", page 22)
– "Track My Tools": "ON/OFF"
(see "TrackMyTools", page 23)
– "Tool"
– "Language"
Under this menu item, you can change the language for
all displays.

– "Time & Date" a
To change the date and time in the display, open the
"Time & Date" submenu. In this submenu you can also
change the date and time format.
To exit the "Time & Date" submenu, press either the
left-hand function button 13 under the tick symbol to
save the settings or the right-hand function button 7 un-
der the cross symbol to discard the changes.
– "Audio signals": "ON/OFF"
Under this menu item, you can switch the audio signals
on or off.
– "Switch-off time"
Under this menu item, you can select the time interval
after which the measuring tool will automatically switch
off if no buttons are pressed. You can also deactivate the
automatic switch-off by selecting the "Never" setting.
– "Delete all images"
Under this menu item, you can delete all the files in the
internal memory at once. Press the right-hand arrow
button 8 for "more ..." to enter the submenu. Then
press either the left-hand function button 13 under the
tick symbol to delete all files, or the right-hand function
button 7 under the cross symbol to cancel the operation.
– "Tool information"
Under this menu item, you can access information about
the measuring tool. There you can find the serial number
of the measuring tool and the installed software version.
You can also press button 17 to exit any menu and return to
the standard display screen.
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 desired measuring
object and press the "Save" button 11. The image is saved in
the camera's internal memory. Alternatively, press the
"Freeze measurement" button 17. The measurement is fro-
zen and shown in the display. This enables you to take as
much time as you need to look at the image. If you do not wish
to save the frozen image, press button 17 to return to meas-
uring mode. If you wish to save the image in the camera's in-
ternal memory, 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 recently
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.
Deleting saved images
Go to the gallery view to delete individual thermal images:
– Press the right-hand function button 7 under the waste
paper basket symbol.
– Confirm the operation by pressing the left-hand function
button 13 or terminate the deletion process by pressing
the right-hand function button 7 under the cancel symbol.
