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 find 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.

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.

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.

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.

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 flashes 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). Confirm 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.

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 flashing 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).

Keep pressing the “MODE” button (6) in the setting menu, until the measuring unit (20) begins to flash. With the “up” 

button (2) and the “down” button (8) the measuring unit can be changed from °C (degrees Celsius) to °F (degrees 

Fahrenheit).

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 flashing 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 find 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.

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 flashing 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) flashes 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 flashing in the display. The visual alarm can be activated or deactivated using 

the buttons “up” (2) and “down” (8).

Remove loose particles with clean compressed air and wipe off remaining residues with a fine brush. Clean the 

surface with a lens cleaning cloth or a clean, soft, lint-free cloth. To remove fingerprints 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.

Use a moist cloth to clean the enclosure. Dry the product after cleaning. Do not use abrasive agents or solvents!

Store the thermometer after use and cleaning in the protective bag. The protective bag protects against dirt, dust 

and damage.
