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.
B. Button Function
℃/℉button: In Measurement Mode, press button “ ”to switch the temperature unit ℃or ℉.
Laser pointer/Backlight button: In Measurement Mode, press button " " to turn on/off backlight; In “HOLD” Mode,
press button “ ” to turn on/off laser pointer.
During measuring, press button “ ” to display MAX/MIN readings.
During measuring, press button “ ” until“ ”icon flashes on the screen, then loose button“ ”, enter into
Emissivity Mode, press button “ ” and“ ”to adjust emissivity value, then keep pressing button " " return
to the normal measurement mode.
C．Battery Replacement
○
1When the low battery icon“ ”appears, replace the meter's battery.
○
2Open the battery compartment, replace the 9V battery and close the battery compartment
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).
