Locating a hot Spot

To find a hot spot aim the thermometer outside the area

of interest, then scan across with an up and down

motion until you locate the hot spot.



Reminders

① Not recommended for use in measuring shiny or

polished metal surfaces ( stainless steel, aluminum,

etc.).See Emissivity

② The unit cannot measure through transparent surfaces

such as glass. It will measure the surface temperature

of the glass instead.

③ Steam, dust, smoke, etc., Can prevent accurate

measurement by obstructing the unit's optics.



Emissivity

Emissivity is a term used to describe the

energy-emitting characteristics of materials.

Most (90% of typical applications) organic materials

and painted or oxidized surfaces have an emissivity of

0.95 (pre-set in the unit). Inaccurate readings will result

from measuring shiny or polished metal surfaces. To

compensate, cove the surface to be measured with

masking tape or flat black paint. Allow time for the tape

to reach the same temperature as the material

underneath it. Measure the temperature of the tape or

painted surface.
