General information
Safety symbols
The following international symbols are used in the device and/or in this
manual:
Declaration of Conformity with EU directives (Conformité Européenne)
Do not dispose of with other household waste
Caution, laser radiation. Class 2 laser device. Risk of eye irritation.
Safety
Before you proceed to operate the camera, acquaint yourself thoroughly with
the present manual and observe the safety regulations and specifications
defined by the producer.
Any application that differs from those specified in this manual may re-
sult in damage to the device and constitute a source of danger for the user.
The camera must not be used in rooms where special conditions are
present e.g. fire and explosion risk.
It is forbidden to use damaged or malfunctioning camera. Do not use any other
adapter than the one supplied with the camera. Repairs may be performed only
by an authorised service point.
KT-128 / 256 / 256F thermal camera is designed to measure and record the images in the infrared. It is designed to provide the user with maximum performance and safety during the work. However, the following guidelines and recommendations must be observed at all times (in addition to all binding precautions applicable at individual work stands and work areas):
26
KT-128 KT-256 KT-256F USER MANUAL
Keep the camera steady when performing the measurements. Do not use the camera
in temperatures exceeding its working and
storage temperature ranges.
Do not direct the camera toward very high intensity radiation
sources such as the sun, lasers or welding arcs etc.
Do not expose the camera to dust and moisture. When operating the
device near water, ensure that it is adequately guarded against splashes.
When the camera is not in use or is to be transported, ensure that the
unit and its accessories are stored in the protective carry case.
Do not re-switch on the camera until 15 seconds later after switching it
off.
Do not throw, knock or shake intensely the camera and its compo-
nents in order to avoid the damage.
Do not attempt to open the camera body, as this action will void the
warranty.
Use only the SD memory card supplied with the camera. During operation, if the
camera is to be moved from hot/cold place to
cold/hot place, e.g. from inside/outside to outside/inside of a room, switch
off the camera and leave it in the new workplace for ca. 60 minutes. Only
after that time, turn it on and start normal operation with an accurate
temperature measurement. Sudden and rapid changes in ambient temperature may
cause fault temperature measurement and even damage camera’s IR detector.
Calibration of the detector during operation, the camera performs au-
to-calibration from time to time, which takes approx. 2 seconds.
Due to continuous development of the instrument’s software,
the actual appearance of the display may slightly differ from the display
presented in this manual.
To maintain required parameters of rechargeable batteries,
unused rechargeable batteries should be charged every 3 months.

repaired by the user. Never attempt to disassemble or modify the camera.
Opening the device will void the warranty.
Use only accessories listed in section 12. Using other acces-
sories does not ensure proper operation of the camera and may cause its
damage.

7 Power supply, battery charging
The camera is powered by an internal rechargeable battery. It may be also powered using the AC adapter.
In order to charge a KT camera, just plug in the AC adapter to the camera USB socket when it is switched off. Charging does not take place during operation of the camera.
If the camera is to be inactive for a long time, it is recommended to recharge the rechargeable battery every 3 months.
Store the half-charged battery pack in a dry, cool and well venti-
lated place and protect them from direct sunlight. The battery pack may be
damaged if stored when fully discharged. The ambient temperature for prolonged
storage should be maintained within the range of 5°C…25°C.
Charge the batteries in a cool, well-ventilated place at a tempera-
ture of 10°C…28°C. Modern fast chargers detect both too low and too high
temperature of rechargeable batteries and react to the situation adequately.
When the temperature is too low, charging should be prevented as it may
irreparably damage the batteries. The increase in temperature of the battery
pack may cause electrolyte leakage and even its ignition or explosion.
Do not exceed the charging current, as it may result in ignition or
“swelling” of the battery pack. “Swollen” battery pack must not be used.
Do not charge or use the batteries in extreme temperatures. Ex-
treme temperatures reduce the lifetime of rechargeable batteries. Always
observe the rated operating temperature. Do not dispose the battery pack into
fire.
Li-Ion cells are sensitive to mechanical damage. This kind of
damage may cause their permanent damage and thus ignition or explosion.
Any interference in the structure of Li-ion battery pack may cause
its damage. This may result in the ignition or explosion.
38
KT-128 KT-256 KT-256F USER MANUAL
A short-circuit of the battery poles “+” and “-” may permanently
damage the battery pack or even cause its fire or explosion.
Do not immerse Li-Ion battery in liquids and do not store in humid
conditions.
If the electrolyte contained in the Lithium-Ion battery pack, con-
tacts eyes or skin, immediately rinse the affected place with plenty of water
and consult a doctor. Protect the battery against unauthorised persons and
children.
When you notice any changes in the Lithium-Ion battery pack (e.g.
changes in colour, swelling, excessive temperature), stop using the battery
pack. Li-Ion batteries that are mechanically damaged, overcharged or
excessively discharged are not suitable for use.
Any misuse of the battery may cause its permanent damage. This
may result in the ignition. The seller and the manufacturer shall not be
liable for any damages resulting from improper handling LiIon battery pack.

8 Cleaning and maintenance
NOTE!
Use the below specified methods of maintenance only. The thermal imager does
not comprise any parts service-
able by the user. Do not at-tempt to dismantle or modify the camera on your
own. Opening the instrument voids the warranty.
Camera enclosure all surfaces, except for optical elements of
the camera, can be cleaned with a soft and moist cloth with generally
available mild detergents. Do not use any solvents or cleaning agents that
could scratch the enclosure (powder, paste, etc.). During cleaning, the camera
must be turned off.
Due to the applied anti-reflective coating, optical lens are the most
sensitive and at the same time the most expensive part of the camera (the lens
is of key importance to radiometric capabilities of the infrared system).
Optical surfaces should be cleaned only, when they are visibly fouled. Do not
touch exposed surfaces of optical lens with fingers, because fouling left with
fingerprints can be harmful to coatings and glass of the lens.
Chemical agents must not be used for cleaning the optics and ac-
cessories of the camera. Use a clean, dry and soft cloth.

9 Storing
When storing the instrument, observe the following guidelines:
make sure the camera and its accessories are dry, allowed are storage
temperatures specified in technical specifica-
tions,
in order to avoid complete discharging of rechargeable batteries
during prolonged storage, charge them once in a while (recommended time: 3
months).
10 Dismantling and disposal
Used-up electrical or electronic equipment must be collected se-
lectively, i.e. must not be mixed with waste of other types.
Used-up electronic equipment must be delivered to an appropriate
collection centre in accordance with regulations related to used-up electrical
or electronic equipment.
Before delivering the equipment to the collection centre do not at-
tempt to dismantle any of its parts.
Follow local regulations related to disposing of packaging, used-
up batteries and rechargeable batteries.
