Thermal imaging features

Turn on / off

To switch on, open the protective flap by sliding it in the
direction of the arrow and thus unlocking it. The un-
locking is audible and noticeable by a clear cracking.
Alternatives in on / off
If the protective flap is damaged or even completely
torn off, e.g. in a particulary harsh use, there is a
further possibility to switch the TILO on and off by
pressing the buttons 1 and 2 simultaneously for at
least one second.
Running time in thermal imaging mode
The running time in the thermal imaging mode
depends on different factors:
– Quality of battery used
– Low ambient temperatures shorten the
running time
– Simultaneous use of the lamp function shortens
the running time, in particular the IR lamp must
be observed. Its simultaneous operation may not
be noticed. The IR lamp operates in a wavelength
range that the thermal sensor cannot detect.
– Bright display lighting reduces runtime
In the pure thermal imaging mode, the running time
under optimum conditions is approx. 3,5 hours.
In order to extend the operating time, there is the
possibility to connect an external power supply. This
will be available as an accessory.

The flap then opens automatically and the thermal
sensor is released. Within two seconds, the device will
boot up and the thermal image will be displayed on
the screen.
If the battery is already heavily drained or used at
very low temperatures (0° to – 20°C), the battery
may not be able to provide the comparatively high
currents required to operate the automatic shutters
(calibration). The device then switches automatically
to manual calibration mode and remains ready for
use. The following has now been changed:
1. If necessary, the shutter flag appears (small
empty square in the lower left corner).
2. If the shutter flag is not responded to with a
manual calibration, the following can occur
deteriorate the image as follows:
– Vignette formation (from the outside
increasing deterioration of contrast)
– possibly vertical stripes
– general contrast reduction
– increased noise
If the unit is started up in very cold conditions or
when the battery is almost empty, the above-men-
tioned restrictions occur at the beginning, but can
also be eliminated by manual calibration. See next
chapter. Altogether, the runtime increases with the
use of manual calibration.
Manual calibration
To perform manual calibration, close the flap for about
0,5 s but do not lock.
Once the manual calibration has been carried out,
automatic calibration no longer takes place. TIt will not
start until the device is switched on again.
Manual calibration results in better image quality and
longer battery life.

Use of rechargeable batteries
The use of rechargeable batteries in a same size as
CR123 batteries is possible, but the run time is reduced
depending on the battery quality by approx. 50 %.
Brightness adjustment
(display brightness)
Press button 1 to change the display brightness.
Each press of the button decreases the brightness
until it reaches the darkest setting. With each
additional pressure the brightness increases again
until the brightest stage is reached. Then the process
starts from the beginning.
The last used setting is saved and automatically
recalled the next time you turn it on.

NOTE
Especially when using at night it is useful to adjust
the display to a very dark level to reduce the glare
effect. If the TILO is then switched on the next
day, the display will appear so dark that it may be
considered defective. Therefore, in the case of a
seemingly black screen, the button 1 should always
be pressed several times.

Zoom

Pressing button 2 briefly switches between the
following zoom levels:
0,8 :
×
This zoom level provides the best overview and
is particularly helpful when it comes to interior
orientation. Since it is a negative zoom, however, the
estimation of distances is difficult.
1 :
×
In this setting, all objects appear on the display in the
same size as in reality. This setting is particularly useful
in the outdoor area for a natural estimation of the
distance to persons or animals.
2 ; 4 and 8 :
× × ×
The higher zoom levels are particularly well suited
for observation and identification. Often in urban
area but also in the forest heat sources are found,
whose origin cannot be determined without prob-
lems. Thus rotting tree stumps, heaps of ants or lar-
ger stones produce distinct thermal signs which can
be mistaken for humans or animals. By means of a
strong zoom setting, objects can be better classified
by observing their movements. Stones for example
tend to move very hardly.
