Malfunction
Possible reason
Correction
The thermal imaging
camera cannot be
switched on. In the
starting process, the
Merlin-42 (2020) swit-
ches off again after
the start logo has
been displayed.
Batteries are too weak.
Insert new batteries.
Can‘t be powered by
an external power
source.
USB cable is damaged.
Replace USB cable.
The image is blurred,
with thin vertical lines
or shadows.
Calibration needed.
Calibrate the image (C
button).
Low image quality/
reduced detection
range.
These problems can occur under adverse we-
ather conditions (high humidity, snowfall, rain, fog,
etc. ). At temperatures above freezing point, the
observed objects (environment and background)
usually show a higher temperature difference. This
can be displayed with correspondingly higher
contrast by the thermal imaging device. At low
outside temperatures, the observed objects cool
down to approximately the same temperature,
so that the temperature contrast is considerably
reduced and the image quality suffers as a result.
This property is due to physics and does not repre-
sent a defect in the thermal imaging camera.
Issues in attached use
The point of impact
position cannot be
adjusted, the values
are not saved.
Instead of the image
shift function, pixel cor-
rection was activated
in the submenu.
see chapter 16
The image disappe-
ars after a shot is fired.
Battery compartment
cover is not seated
correctly.
Check cover for tight
fit (seal should not be
visible from the outside).
Minimum distance
of the mounting not
maintained.
Check and correct
distance (see chapter
16).
The point of impact is
not constant.
-
Check clamping
adapter and mounting
for tight fit.
The memory location
of the image shift
coordinates incorrectly
selected .
see chapter 14
The parallax adjustment
on the daylight scope is
not set to infinity.
Set parallax adjustment
to infinity.
Minimum mounting
distance not observed
Check and correct
distance (see chapter
16).
