b) Function
• Infrared thermometers measure the surface temperature of an object. The sensor on the product records
the heat radiation emitted, reflected and transmitted through the object, and converts this information into
a temperature value.
• To measure transparent materials, apply a layer of opaque adhesive tape to the surface of the object.
Allow the tape to reach the temperature of the object, and then point the thermometer at the tape.
• Emissivity is used to describe the energy emission characteristics of a material. The higher the emissivity,
the more radiation a material can emit. Many organic materials and surfaces have an emissivity of
approx. 0.95; metallic surfaces or shiny materials have a lower emissivity and may lead to inaccurate
readings. The thermometer's emissivity settings cannot be changed.
Emissivity of different surfaces
The emissivity levels listed in the following table are approximate values. Parameters such as
the shape and characteristics of the material can affect the emissivity of an object. Measuring
materials with an emissivity that is different from the preset emissivity may lead to slightly
inaccurate readings.
Surface Emissivity
Asphalt 0.90 – 0.98
Varnish (matt) 0.97
Concrete 0.94
Human skin 0.98
Ice 0.96 – 0.98
Mortar 0.89 – 0.91
Ferric oxide 0.78 – 0.82
Paper 0.70 – 0.94
Soil/humus 0.92 – 0.96
c) Switching on the thermometer
• Press the trigger (1) to switch on the thermometer.
d) Measuring the surface and air temperature
• Press the Mode button (5) until
appears on the LCD display. The
will be displayed when the thermometer is measuring the temperature. The temperature displayed is the
air temperature.
• Press the Mode button until appears on the LCD display. The
displayed when the thermometer is measuring the temperature. The temperature displayed is the surface
temperature of the measured object.
Make sure that the lens of the infrared sensor is clean. Dust, smoke or fluff on the lens may
distort the results.
• When measuring the air temperature, hold the thermometer in an open space.
• Hold the thermometer perpendicular to the object that you want to measure and point the laser (3) at the
object. Make sure that the object is not smaller than the IR measuring spot (see "e) IR measuring spot
size" for more information).
• Press and hold the trigger (1) to measure the temperature. "SCAN" (E) will appear on the display while the
temperature is being measured.
• The measured value will be displayed on the temperature display (A). The displayed value is the average
surface temperature of the IR measuring spot.
• After releasing the trigger, "HOLD" (F) will be displayed together with the last measured value.
• To locate hot or cold spots on the measured object, pull the object towards you and move the laser beam
up and down while you observe the measurements. The laser beam indicates the measured area. When
you release the trigger, the thermometer turns off automatically after 10 seconds if no other buttons are
pressed.
• "Hi" will be displayed if the temperature exceeds the measuring range (> 602°C). "Lo" will be displayed if
the temperature is lower than the measuring range (<-52°C).
e) IR measuring spot size - distance-to-spot ratio (D/S)
• In order to obtain precise measuring results, the measured object must be larger than the IR measuring
spot. The measured temperature is calculated using the average temperature of the measured area. The
smaller the object, the closer it must be to the thermometer. The exact size of the measuring spot is shown
in the following diagram. It is also indicated on the thermometer. To ensure precise measurements, the
measured object should be at least twice the size of the measuring spot.
Configuring the settings
• The thermometer must be switched on using the trigger button (1) in order to change settings.
• Press the Mode button (5) to switch the thermometer setting on.
a) Changing the temperature unit (°C / °F)
The temperature can be displayed in °C and °F.
• Press and hold the Mode button for 3 seconds. Press the trigger (1) to switch the unit from °C (degrees
Celsius) to °F (degrees Fahrenheit). The selected unit will be displayed on the LCD.
• Press and hold the Mode button to confirm the setting.
b) Switching the backlight on and off
• Press the Mode button (5) to switch the thermometer setting on.
• Press and hold the Mode button for 3 seconds. Briefly press the Mode button again. To turn on the
backlight, hold down the trigger (1) until "1" appears on the display. To turn off the backlight, hold down the
trigger (1) until "0" appears on the display.
• Press and hold the Mode button for 3 seconds to confirm the setting.

c) Switching the laser on and off
The target laser can be switched on and off. When the laser is switched on, the laser symbol (triangle with
radiation symbol) is shown on the display.
• Press the Mode button (5) to switch the thermometer setting on.
• Press and hold the Mode button (5) for 3 seconds. Release the Mode button and then press it again twice.
To disable the laser, hold down the trigger (1) until "0" appears on the display. To enable the laser, hold
down the trigger (1) until "1" appears on the display. The laser will be automatically turned on when you
take a measurement.
• Press and hold the Mode button for 3 seconds to confirm the setting.
To scroll through the settings, press the Mode button (5) to go the next setting. To exit the
settings, press and hold the Mode button for 3 seconds. All three settings will be automatically
confirmed when you exit the settings.
Cleaning
• Before cleaning the thermometer, disconnect it from the power supply by removing the battery. Do not
submerge the thermometer in water.
• Never use aggressive detergents, rubbing alcohol or other chemical solutions, as these could damage the
casing or cause the thermometer to malfunction.
• Remove loose particles from the lens with clean compressed air, and then wipe off any remaining residue
with a fine lens brush. Clean the surface of the lenses using a lens cloth or a soft, lint-free cloth. The cloth
can be moistened with water or a lens cleaning solution to remove fingerprints and other residues. Do not
use a rough, fluffy cloth to clean the lens. Avoid applying too much pressure when cleaning the lens.
• Use a dry, lint-free cloth to clean the product housing.
