5.5. Shutter
• The thermal image of the Thermal Imager becomes blurry, when the
Thermal Imager is not correcting after some minutes or the Thermal
Imager changes target.
• To get thermal image, the Thermal Imager correct itself. a clearer will
• The Thermal Imager has two modes for correcting, Manual and Auto
mode.
• In Manual Mode, hold down the down arrow button, the Thermal Imager
will correct.
• In Auto Mode, the Thermal Imager can correct automatically while the
thermal image of the Thermal Imager becomes blurry.
5.6. Temperature Measurement
• All objects radiate infrared energy.
• The quantity of energy radiated is base on the actual surface temperature
and the surface emissivity of the object.
• The Thermal Imager senses the infrared energy from the surface of the
object and uses this data to calculate an estimated temperature value.
• Many common objects and materials such as painted metal, wood, water,
skin, and cloth are very good at radiating energy and it is easy to get
relatively accurate measurements.
• For surfaces that are good at radiating energy (high emissivity). The
emissivity factor is >0.90.
• This simplification does not work on shiny surfaces or unpainted metals
as they have an emissivity of <0.6. These materials are not good at
radiating energy and are classified as low emissivity.
• To more accurately measure materials with a low emissivity, an emissivity
correction is necessary.
• Adjustment to the emissivity setting will usually allow the Thermal
Imager to calculate a more accurate estimate of the actual temperature.
• For more information please see Emissivity Adjustment to get the most
accurate temperature measurements.
5.7. Emissivity Adjustment
• The correct emissivity value is important to make the most accurate
temperature measurement.
• Emissivity of a surface can have a large effect on the apparent
temperatures that the Thermal Imager observes.
• Understanding the emissivity of the surface, but may not always, allow
you to obtain more accurate temperature measurements.
Note: Surfaces with an emissivity of <0.60 make reliable and consistent
determination of actual temperature problematic. The lower the emissivity,
