Page 16: Notes
10. Notes 10.1 Work Principle The infrared thermometer is designed for measuring surface temperature of an object. The optical sensor can emit, reflect and transmit energy, which is collected and focused on a detector, then translate it into the temperature reading by electronics and displayed on the LCD screen. - Page 17 As distance (D) from the object increases, the spot size (S) of the area measured by the unit becomes larger. 10.4 Locating a hot spot To find a hot spot, first aim the thermometer to the outside of target area, then scan across in an up and down motion until the hot spot is located.
