Any application that differs from those specified in the present manual may result
in a 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 and is partially or fully
out of order.
In case the camera is not used for a long time, its batteries should be removed.
It is not allowed to use the camera with half-closed or opened battery cover and
do not use any other power adapter than the one supplied with the camera.
Repairs may be carried out only by an authorised service point.
KT-640 Thermal Imager is designed to measure and record the images in the infrared.
The camera is constructed in a manner which gives you maximum performance and safe-
ty at work, however the following precautions must be adhered to at all times (in addition
to any advised precautions applicable at the relevant work-site or work area):
Keep the camera steady during operation.
Do not use the camera in ambient temperatures exceeding its operation 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 jam the loudspeaker holes on the camera body.
Do not re-switch on the imager before 30 seconds after switching it off and do
not remove the battery while operating the instrument.
Do not throw, knock or shake intensely the camera and its components in order
to avoid the damage.
Do not attempt to open the imager body, as this action will void the warranty.
Keep the SD memory card for the exclusive use of 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 the imager off and
leave it in the new workplace for 20 minutes, then 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.

FPA setting (FPA -. Focal Plane Array): in order to ensure accurate temperature
measurement, the FPA detector was calibrated in different temperature points. After
switching the imager on, it performs auto calibration procedure (3 times during the
first minute). During the calibration, for about 2 seconde, the device does not
respond to user’s activity ( it is indicated by „calibration” word on screen).
Apart from that, autocalibration, of 2 seconds duration, performs automaticly
during operation of the device, and is dependent on external conditions and i salso
indicated by „calibration” word displayed on screen.
Calibration can be performed manually at any time. In order to do that you need
to go to real time mode screen by pressing C button (6) as many times until there is
only infrared image being displayed on screen with central point selected. Then you
need to press and hold C button for 2 seconds –calibration procedure will be per-
formed, and it will be indicated by „calibration” note on screen.
During imager operation its housing temperature increases and it’s a normal
phenomenon.
NOTE!
KT-160 Thermal camera has no parts that could
be repaired by its user. Never attempt
to dismantle or modify the camera. Opening the unit
invalidates the warranty.
NOTE!
Laser pointer installed in the camera may be
dangerous to eyes, in case of direct contact!
DO NOT DIRECTED THE LASER BEAM TOWARDS OTHER PERSONS OR
ANIMALS!
Please note that the laser beam may reflect off
shiny surfaces.
