2. INTENDED USE
The IR-260-8S is a device for non-contact temperature measurement, which uses the infrared
energy emitted by an object to determine the temperature. The IR-260-8S thermometer is ideal
for measuring the temperature of hot, hard-to-reach, or moving objects. It measures the surface
temperature of an object. However, it cannot make measurements through transparent surfaces
such as glass or plastic. The thermometer has a temperature range of -30ºC to 260ºC. Power is
supplied by a 9 V battery.
Measurements must not be carried out under unfavourable ambient conditions. Adverse ambient
conditions include:
• Moisture or excessive humidity
• Dust or combustible gases, vapours or solvents
• Thunderstorms or conditions as during a storm (e.g. strong electrostatic fi elds should be
avoided)
This product fulfils European and national requirements related to electromagnetic
compatibility (EMC). CE conformity has been verified and the relevant statements and
documents have been deposited at the manufacturer.
Unauthorised conversion and/or modification of the device are inadmissible because of safety
and approval reasons (CE). Any usage other than described above is not permitted and can
damage the product and lead to associated risks such as short-circuit, fire, electric shock, etc.
Please read the operating instructions thoroughly and keep them for further reference.

• The product must not be exposed to electromagnetic fields, static electrical fields, extreme
temperatures, direct sunlight or dampness.
• If there is reason to believe that safe operation is no longer possible, put the device out of
operation and secure it against unintended operation. Safe operation is no longer possible if:
- the product shows visible damages,
- the product no longer works and
- the product was stored under unfavourable conditions for a long period of time,
- the product was subject to considerable transport stress.
• The product should not be connected immediately after it has been brought from an area of cold
temperature to an area of warm temperature. Condensed water might destroy the product. Wait
until the product stabilises to adapt to the new ambient temperature before use.
• The device must not be exposed to humidity or liquids.
• Steam, dust, smoke and/or vapours can prevent accurate measurement by obstructing the
Version 03/11
thermometer's optics.
• The manufacturer or supplier accepts no responsibility whatsoever for incorrect displays or the
consequences which can arise from such incorrect displays.
Laser
• Never look into the laser beam and never point it at people or animals. Laser radiation can
cause damage to eyes or skin.
• This product is equipped with a class 2 laser according to EN 60 825-1. Never open the device.
• Any adjustment or service work is only to be carried out by qualified personnel who are
familiar with the risks involved. Improperly made adjustments may result in hazardous laser
radiation.
• During operation of the device, the laser has to be directed in such a way that no person is
located within the range of projection and that unwanted reflected rays (e.g. due to reflecting
objects) do not get into the range of any person.
• If possible, restrict the range of radiation by using screens or partitions.
• Never open the device. Any adjustment or service work is only to be carried out by qualified
personnel who are familiar with the risks involved. Improperly made adjustments may result
in hazardous laser radiation.
• Included in the delivery are reference signs for the laser in different languages. In case the
sign on the laser is not written in the language of your country, please fix the respective sign
onto the laser.
Battery
• Observe correct polarity while inserting the battery.
• Remove the battery if the device is not used for a long period of time to avoid damage through
leaking. Leaking or damaged batteries might cause acid burns when contact with skin,
therefore use suitable protective gloves to handle corrupted batteries.
• Keep batteries out of reach of children. Do not leave the battery lying around, as there is risk,
which children or pets could swallow it.
• Make sure that batteries are not dismantled, short-circuited or thrown into fire.
• Never recharge non-rechargeable batteries. There is a risk of explosion!
Miscellaneous
• The product must not be used for medical or public purposes.
• Repair works must only be carried out by a specialist/ specialist workshop.
• If you have queries about handling the device, that are not answered in this operating
instruction, our technical support is available under the following address and telephone

7. INSERTING THE BATTERIES
1. Replace the battery as soon as the low battery symbol appears on the display.
2. Open the battery compartment cover.
3. Connect the 9 V battery to the battery connector. The 9 V battery can only be inserted one way
and hence cannot have the wrong polarity. Do not use force to insert the battery.
4. Close the battery compartment cover.
8. OPERATION
Operating principle
IR thermometers measure the surface temperature of an object. The sensor on the device
records the heat radiation emitted, reflected and transmitted from the object, and converts this
information into a temperature value. The emission levelis a value used to describe the energy
radiation characteristics of a material. The higher the value, the more capable the material is of
emitting radiation. Many organic materials and surfaces have an emission level of approx. 0.95.
Metallic surfaces or shiny materials have a lower emission level and therefore return inaccurate
measured values.
Measurement distance / measurement surface area ratio (D/S)
• To achieve accurate measurements, the target must be larger than the thermometer's
measuring area. The measured temperature is the average temperature of the area
measured.
• The smaller the target, the smaller the measurement distance between thermometer and
target object has to be.
• The distance to target / size of IR focal spot ratio is 8:1. With a distance of 8 cm to the target,
the size of the IR focal spot is thus 1 cm.

Measuring
1. To obtain the best measurement results, orient the infrared sensor of the thermometer
vertically to the target object surface.
2. Hold down the trigger to start the measurement. "SCAN" appears on the display.
3. The measured temperature is shown on the display.
4. While holding down the trigger, press the "LCD/Laser" button
- once to activate the laser pointer (laser symbol appears on the display),
- twice for additionally activating the LCD backlight,
- three times to switch off the laser pointer, or
- four times to switch off the LCD backlight.
5. After the trigger has been released the measured value is saved for approx. eight seconds.
"HOLD" appears on the display.
6. The thermometer switches off automatically after eight seconds of inactivity.
• Press the "ºC/ºF" button to switch between the two units.
• The device saves the measured maximum and minimum temperatures during the
current measurement. Press the "MAX/MIN" button to show these values in the
lower part of the display.
9. CARE AND MAINTENANCE
Lens cleaning: Blow off loose particles using clean compressed air and then brush the remaining
debris away with a fine lens brush. Wipe the surface with a lens cleaning cloth or a clean, soft, lint-
free cloth. In the case of fingerprints or any other grease formation, the cloth may be moistened
with water or lens cleaning fluid. Do not use acid, alcohol, or other solvents or harsh, linty cloth to
clean the lens. Avoid and excessive pressure.
Cleaning the exterior: To clean the exterior housing, use soap and water or a mild commercial
cleaner. Do not use abrasive or solvents!
