• Use extreme caution when the laser beam is turned on.
• Do not point the beam toward anyone or any animals.
• Do not allow the beam to strike the eye from a reflective surface.
• Do not use the laser near explosive gases.

Comply with EMC

Field of View

The meter's field of view is 30:1, for example, if the meter is 30 inches from the target spot, the diameter of the target must be at least 1 inch.

Other distance ratios are shown below in the field of view diagram.

Operating Instruction

1. 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.
2. Button Function
   1. ℃/℉button: In Measurement Mode, press button " "to switch the temperature unit ℃ or ℉.
   2. 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.
   3. During measuring, press button " " to display MAX/MIN readings.
      During measuring, press button "" 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.
3. Battery Replacement
   1. When the low battery icon""appears, replace the meter's battery.
   2. Open the battery compartment, replace the 9V battery and close the battery compartment
      

Notes

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.
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.
3. Distance & Spot Size
   • As distance (D) from the object increases, the spot size (S) of the area measured by the unit becomes larger.
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.
5. Notice
   • 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.
6. Maintenance
   • 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.
7. Emissivity
   • Most (90%) organic materials and painted or oxidized surfaces have an emissivity of 0.95 (pre-set in the unit).
