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.
The laser is used for aiming the target object only.
10.2 Field of View
The object under test should be larger than the spot size
calculated by the field of view diagram.
The smaller the target object is, the closer the meter should be
to it for accurate measuring.
When accuracy is critical, make sure the target is at least twice
as large as the spot size.
