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.
OPERATION
a) 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.
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 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!
DISPOSAL
a) Product
Electronic devices are recyclable waste and must not be disposed of in the household
waste.

b) (Rechargeable) batteries
You as the end user are required by law (Battery Ordinance) to return all used batteries/
rechargeable batteries. Disposing of them in the household waste is prohibited.
Contaminated (rechargeable) batteries are labelled with this symbol to indicate that
disposal in the domestic waste is forbidden. The designations for the heavy metals
involved are: Cd = Cadmium, Hg = Mercury, Pb = Lead (name on (rechargeable)
batteries, e.g. below the trash icon on the left).
Used (rechargeable) batteries can be returned to collection points in your municipality,
our stores or wherever (rechargeable) batteries are sold.
You thus fulfil your statutory obligations and contribute to the protection of the environment.
