Inserting the batteries
• Replace the battery as soon as the low battery symbol appears on the display.
• Open the battery compartment cover.
• 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.
• Close the battery compartment cover.
Operation
a) Operating principle
IR thermometers measure the surface temperature of an object. The sensor on the device records the heat
radiation emitted, reected 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.
b) 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.

c) 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.
Care and maintenan
Lens cleaning: Blow off loose particles using clean compressed air and then brush the remaining debris
away with a ne lens brush. Wipe the surface with a lens cleaning cloth or a clean, soft, lint-free cloth. In the
case of ngerprints or any other grease formation, the cloth may be moistened with water or lens cleaning
uid. 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!
Disposal
a) General
Electronic products are recyclable material and do not belong in the household waste. When the
device has become unusable, dispose of it in accordance with the current statutory regulations.
Remove any inserted batteries and dispose of them separately from the product.
b) Batteries/rechargeable batteries
As the end user, you are required by law (Battery Ordinance) to return all used batteries/
rechargeable batteries; disposal of them in the household waste is prohibited!
Batteries/rechargeable batteries containing hazardous substances are labelled with these
symbols to indicate that the disposal of them in the household waste is forbidden. The symbols
for dangerous heavy metal constituents are: Cd=Cadmium, Hg=Mercury, Pb=Lead (name
written on the battery/rechargeable battery, e.g., under the rubbish bin symbol on the left).
You can return your used batteries/rechargeable batteries free of charge at the ofcial collection points of
your community, in our stores, or at places where batteries or rechargeable batteries are sold!
You thereby full your statutory obligations and contribute to the protection of the environment.
