Display Resolution

The level of precision to which a temperature value can be displayed, usually expressed in degrees or tenths of degrees.

Drift

The change in instrument indication over a long period of time, not caused by external influences on the device (per the ASTM standard test method E 1256-88).

EMC

Electro-Magnetic Compatibility is the resistance to electrical signal disturbances within IR thermometers.

Emissivity

Emissivity is the ratio of infrared energy radiated by an object at a given temperature and spectral band to the energy emitted by a perfect radiator (blackbody) at the same temperature and spectral band. The emissivity of a perfect blackbody is unity (1.00).

EMI/RFI Noise

Electro-Magnetic Interference/Radio Frequency Interference (EMI and RFI) may cause disturbances to electrical signals within IR thermometers. EMI and RFI noise is most commonly caused by devices by switching motors (air conditioners, power tools, refrigeration systems, etc.).

°F (Fahrenheit)

Temperature scale where θF (θC υ 1.8) 32 θR 459.67 .

Far Field

A measured distance substantially greater than the focus distance of the instrument; typically greater than 10 times the focus distance.

Field of View (FOV)

The region, at the target, measured by the IR thermometer. Typically presented by giving the spot diameter as a function of distance from the instrument. Also presented as the angular size of the spot at the focus point.
