INSERTING THE BATTERIES
• Replace the battery as soon as the low battery symbol appears on the display.
• Open the battery compartment cover.
• C onnect 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
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 charac-
teristics 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)
• T o 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.
• T he smaller the target, the smaller the measurement distance between thermometer and target
object has to be.
• T he 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 Distance (mm)
Measuring
1. T o 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.
T he 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) General
b) Batteries/rechargeable batteries
As the end user, you are required by law (Battery Ordinance) to return all used batteries/rechargea-
ble batteries; disposal of them in the household waste is prohibited!
You can return your used batteries/rechargeable batteries free of charge at the official collection
points of your community, in our stores, or at places where batteries or rechargeable batteries are
sold!
You thereby fulfil your statutory obligations and contribute to the protection of the environment.
