To determine the hottest spot on the measured object you have to “scan” the object with measuring button (7)
held down, performing systematic zigzag movements until you nd the hottest spot. The highest measured
temperature is shown in the upper right of the display as maximum temperature (if Max function is selected).
In order to obtain exact measured values, the infrared thermometer has to be adjusted to the ambient
temperature. Allow the product to adjust to the ambient temperature after relocation.
Shiny surfaces affect the measured result. To compensate, the shiny part of the surface can be covered with
adhesive tape or matt black paint. The product cannot take measurements through transparent surfaces such
as glass. Instead, it measures the surface temperature of the glass.
Longer measurements of high temperatures, with close measuring distance, lead to self-heating of the
measuring device and thus to inaccurate measurements. In order to obtain exact measured values,
remember the following rule of thumb: The higher the temperature the greater the measuring distance and
the shorter the measuring time.
c) IR measuring spot size - Distance to surface level (Distance to spot level; D/S)
In order to obtain precise measured results, the object to be measured must be larger than the measuring IR spot of
the IR thermometer. The temperature recorded is the average temperature of the area measured. The smaller the
object to be measured, the shorter the distance must be to the infrared thermometer. The exact size of the measuring
spot is indicated in the following diagram. It is also printed on the device. For precise measurements, the object to be
measured should be at least twice the size of the measuring spot.
d) Target laser
The target laser can be activated or deactivated. Turn the measuring device on by pressing the measuring button (7).
Press the “Laser/background illumination” button (3). When the laser is activated, the laser display (triangle with
radiation symbol) is shown in the display. To deactivate the laser, press the “Laser/background illumination” button (3)
until the laser display goes out.
e) Background illumination
With the measuring device running, use the button “Laser/Background illumination” (3) to activate/deactivate the
display’s background illumination. Press this button, until the background illumination is activated or deactivated.
SETTINGS MENU
The product is equipped with a setting menu. To get into the menu, press and hold down the “MODE” button (6) while
the product is turned on until the degree of emission ashes in the display. Now press the “MODE” button, until you
get to the desired settings function in the menu. The values on the settings menu can be changed by using the “up”
button (2) and the “down” button (8). Conrm your input with the measuring button (7), or press the “MODE” button (6)
in order to move to the next setting. When the device is switched off, the set values remain stored.
a) Min/Max measurement
The product can indicate in the secondary display (15) the lowest (MIN) or the highest (MAX) temperature value that
occurs during the measurement. In the setting menu, press the “MODE” button (6) until the display “MIN” (19) or
“MAX” (13) starts ashing in the display. Select the desired display type for the secondary display (15) (MIN or MAX),
by using the buttons “up” (2) and “down” (8).
b) “°C/°F” conversion between measurement units
Keep pressing the “MODE” button (6) in the setting menu, until the measuring unit (20) begins to ash. With the “up”
button (2) and the “down” button (8) the measuring unit can be changed from °C (degrees Celsius) to °F (degrees
Fahrenheit).
c) Setting the emission level
The measuring device allows the emission level to be set. Thus, different materials and surfaces can be measured
precisely (also refer to chapter “a) Operating principle”).
Keep pressing the “MODE” button (6), until the symbol for the emission level (14) starts ashing in the display. Using
the buttons “up” (2) and “down” (8) the emission level can be adjusted from 0.10 to 1.00 depending on the object
to be measured.
Following the technical data you will nd a table with typical materials and their emission level. Many
organic materials have an emission level of 0.95. Thus the default setting for the emission level is 0.95.
The emission level of a surface can be measured with a conventional thermometer with a special surface
sensor. Measure the temperature of the surface to be measured with a conventional thermometer.
Change the emission level of the infrared thermometer until the measured value (18) matches that of the
conventional surface measurement. This, however, is only necessary for highly precise measurements.
d) Alarm mode
The measuring device has an alarm function for cases where a set temperature value is exceeded. The alarm is
indicated by a beeper and the background illumination ashing red. Due to this function, the measuring device is ideal
for monitoring, etc. The alarm is triggered when the set alarm value is exceeded.
Keep pressing the “MODE” button (6), until the symbol for alarm “SET HIGH” (17) ashes and a temperature value
is shown in the display. Using the buttons “up” (2) and “down” (8) set the alarm value that will trigger the alarm if it
is exceeded.
The acoustic alarm (beeper) can be deactivated. Keep pressing the “MODE” button (6) in the settings menu, until the
symbol for the visual alarm (16) starts ashing in the display. The visual alarm can be activated or deactivated using
the buttons “up” (2) and “down” (8).
MAINTENANCE AND CARE
a) Cleaning of the lens
Remove loose particles with clean compressed air and wipe off remaining residues with a ne brush. Clean the
surface with a lens cleaning cloth or a clean, soft, lint-free cloth. To remove ngerprints and other fat residues, the
cloth can be moistened with water or lens cleaning solution. Do not use any acidic, alcoholic or other solvents or
rough, linty cloth to clean the lens. Avoid applying too much pressure during cleaning.
b) Cleaning the housing
Use a moist cloth to clean the enclosure. Dry the product after cleaning. Do not use abrasive agents or solvents!
c) Protective bag
Store the thermometer after use and cleaning in the protective bag. The protective bag protects against dirt, dust
and damage.
DISPOSAL
a) Product
Electronic devices are recyclable waste and must not be disposed of in the household waste.
At the end of its service life, dispose of the product according to the relevant statutory regulations.
Remove any inserted (rechargeable) batteries and dispose of them separately from the product.
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 full your statutory obligations and contribute to the protection of the environment.
