10. Notes
⑴Work 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.
⑵Field 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.
⑶Distance & Spot Size
● As distance (D) from the object increases, the spot size (S) of the area measured by the unit becomes larger.
⑷Locating 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.
⑸Notice
● Not recommend for measuring shiny or polished metal surfaces like stainless steel, aluminum, etc.
● Do not make measurement through transparent surface such as glass.
● If the surface of the object under test is covered with frost, oil, grime, etc., clean before taking measurement.
⑹Maintenance
● Do not use volatile liquids to clean the unit, swipe it with dry soft cloth.
● Do not disassemble the unit, repair it by qualified personnel
● Do not immerse it in water.
● Do not store it in high temperature or humidity.
⑺Emissivity
● Most (90%) organic materials and painted or oxidized surfaces have an emissivity of 0.95 (pre-set in the unit).
