OPERATING INSTRUCTIONS
Never aim the laser beam pointer at the eyes of a person or animal or 
an object other than the work piece.
Follow these steps to measure surface temperature of an object in most applications. See next section for additional 
measurement features. 
1.    Aim the thermometer at the object and squeeze the trigger for at least 3 seconds, “SCAN” icon will appear on the 
display during measurement. Use the laser pointer to aim at the object more accurately. 
2.   Release the trigger to display the “Most Recent” temperature reading. The display will “Remain” and automatically 
will shut off after Approximately 1 minute.
3.    For accurate temperature measurement ALWAYS follow the D:S (11:1) ratio rule. For example, if the diameter 
of the surface (S) is 1 ft., the distance (D) between the IR thermometer and surface should be LESS than 11 ft. 
For the most accurate readings, the distance between the thermometer and the target should be 1/2 of D or 
  1/2 x D:S x target diameter. For our example: 
Optimum Distance = 1/2 x 11 x 1ft = 5.5ft for the target diameter of 1ft.
NOTE: Temperature measurement will not be accurate off shiny objects (such as stainless 
steel, gold, aluminum wrapping) or through glass or windows.
