5. Field of View
The meter's field of view is 30:1, for example, if the m eter is 30 inches
from the target spot, the diameter of the target m ust be at least 1 inch.
Other distance ratios are shown below in the field of view diagram.

9. Operating Instruction
A. Operating steps:
○
1 Hold the meter by its handle grip and point it toward the surface to be measured.
○
2 Pull and hold the Trigger to turn the meter on, the "SCAN" icon will appear and begin testing.
○
3 The surface temperature being tested will be displayed on the LCD screen.
○
4 Release the trigger, the "HOLD" icon will appear, and the reading will be held for several seconds.
○
5 The meter will automatically shut off after 20 seconds of inactivity.
Measurement Note： If the meter used in an ambient temperature with wide temperature change, awaiting at least 30
minutes to adjust it.
The laser is designed for aiming only; it can be shut off while operating in short distance to save the battery.

10. Notes
⑴ 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 focuse d 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.
⑵ 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 critica l, make sure the target is at least twice as large as the spot size.
⑶ Distance & Spot Size
● As distance (D) from the object incr eases, the spot size (S) of the area measured by the unit becomes larger.
⑷ Locating a hot spot
● To find a hot spot, first aim the thermometer to the outside of target area, then scan across in a n up and down motion
until the hot spot is located.
⑸ Notice
● Not recommend for measuring shiny or polished metal surfaces like stainless steel, aluminum, etc.
● Do not make m easurement through transparent surface suc h as glass.
● If the surface of the object under test is covered with frost, oil, grime, etc., clean before taking measurement.
⑹ Maintenan ce
● 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.
⑺ Emissivity
● Most (90%) organic ma terials and painted or oxidized surfaces have an emissivity of 0.95 (pre-set in the unit).
