KEILER-1
Malfunction Possible reason Remedy
The thermal imager cannot
be switched on.
In the starting process, the
KEILER-1 switches off again
after the start logo has
been displayed.
The battery is not
sufficiently charged.
Charge the battery for half an hour before
switching the unit on again.
The device cannot be pow-
ered by an external pow-
er source.
The external power
source is not strong
enough.
Use an external power source with a min.
charging current of 5 V / 2 A.
The USB cable is
damaged.
Replace the USB cable.
The battery is very slow to
charge.
Using a power supply
unit with insufficient
power.
Use only the KEILER-1 power supply unit
supplied.
The device is not
switched off.
Switch the device off (OFF) so that charging
works reliably.
The battery is deeply
discharged.
Charging takes a significantly longer time
for deeply discharged batteries.
The image is blurred, with
thin vertical lines or shad-
ows.
Calibration needed. Perform an image calibration.
After calibration, a "ghost
image" can be seen super-
imposed on the scene.
Calibration mode S
was selected and
the front lens was
not covered during
calibration.
Perform a repeat calibration with the front
lens covered.
Low image quality / re-
duced detection range.
These problems can occur under adverse weather conditions (high
humidity, snowfall, rain, fog, etc.).
During long periods of constant weather conditions without
sunshine, and especially in rainy weather, the observed objects
converge to approximately the same temperature, so that the tem-
perature difference is considerably reduced, and the image quality
suffers as a result. This circumstance is due to physical causes and is
not a defect of the thermal imager.
