OPERATING INSTRUCTIONS
USING THE LASER POINTER FEATURE
Your Digital Infrared Thermometer is equipped with a laser pointer feature that helps you accurately target the object you are attempting to measure. While pulling the trigger, press the LASER key (FIGURE 1). Repeat to turn the laser pointer feature off.
USING THE BACKLIGHT FEATURE
The back light feature allows you to easily read the LCD display when working in dim conditions. While pulling to trigger, press the BACKLIGHT key (FIGURE 1). Repeat to turn the backlight off.
SETTING THE TEMPERATURE UNITS
With your Digital Infrared Thermometer, you have the flexibility to switch temperature units between
˚F or ˚C. While pulling the trigger, press the F/C key (FIGURE 1) until the desired unit is shown on the LCD.
SETTING THE EMISSIVITY
All surfaces emit thermal radiation. Depending on the temperature, composition and finish of an object, there is a maximum amount of radiation that any given surface can emit. An object that absorbs all (and reflects none) of the radiation falling upon it is called a blackbody and has an emissivity value of 1.0. However, most surfaces are not blackbody emitters and will emit only a fraction of thermal radiation that a blackbody would at the same temperature.
FIGURE 2 lists the emissivity settings you should use for common objects. Depending on the composition of the object you are attempting to measure, you may need to adjust the emissivity setting on your Digital Infrared Thermometer. If you are unsure of which emissivity setting to use, keep in mind that
an emissivity setting of 0.95 will cover 90% of typical applications.
