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 in-side/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 meas-urement and even damage camera’s IR detector.
Calibration of the detector – during operation, the camera performs auto-calibration from time to time, which takes approx. 2 seconds and which is signalled by “Calibration” message at the bottom of the screen.

NOTE:

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 batter-ies should be charged every 3 months.

CAUTION!

KT-120M thermal camera has no parts that could be 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 11. Using other accessories does not ensure proper operation of the camera and may cause its damage.

Display

During the operation of the camera, the infrared image is displayed in real- time on the screen. The temperature of the object is displayed for the whole time.

Quick start

The camera is not a diagnostic / medical equipment. The measurement result cannot be used as a basis for medical diagnosis.
The external body temperature does not match the internal temperature, as measured with a traditional thermometer.
In justified cases, the measurement should be verified using devices having a medical certificate for hu-man body temperature measurement.

Turning the camera ON/OFF

In order to switch the camera on, press and hold button for more than 3 sec. The camera will display the welcome logo and commence the start-up, including the self-check. After completing the self-check, the camera is ready to work and enters the mode of real-time display of infrared image.
To switch OFF the camera press and hold button until the screen goes blank.

NOTE: In order to obtain the correct indications, the camera must stabilize them. Stabilization may take ca. 10 minutes after the instrument is turned on.

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 micro 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.

General rules for using Li-Ion rechargeable batteries

Store the half-charged battery pack in a dry, cool and well ventilated place and protect them from di-rect sunlight. The battery pack may be damaged if stored when fully discharged. The ambient tem-perature 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 temperature 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 ir-reparably damage the batteries. The increase in temperature of the battery pack may cause electro-lyte 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. Extreme temperatures reduce the life-time 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.
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, contacts eyes or skin, immediately rinse the affected place with plenty of water and consult a doctor. Protect the battery against unauthor-ised persons and children.
When you notice any changes in the Lithium-Ion battery pack (e.g. changes in colour, swelling, ex-cessive 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 Li-Ion battery pack.

Cleaning and maintenance

NOTE!

Use the below-specified methods of maintenance only.
The thermal imager does not comprise any parts serviceable by the user. Do not attempt 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 lenses are the most sensitive and at the same time the most expensive part of the camera (the lens is of key importance to the 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 the coatings and glass of the lens.
Chemical agents must not be used for cleaning the optics and accessories of the camera. Use a clean, dry and soft cloth.

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 specifications,
in order to avoid complete discharging of rechargeable batteries during prolonged storage, charge them once in a while (recommended time: 3 months).

Dismantling and disposal

Used-up electrical or electronic equipment must be collected selectively, i.e. must not be mixed with waste of other types.
Used-up electronic equipment must be delivered to an appropriate collection center in accordance with regulations related to used-up electrical or electronic equipment.
Before delivering the equipment to the collection center do not attempt to dismantle any of its parts.
Follow local regulations related to disposing of packaging, used-up batteries, and rechargeable batteries.
