Glossary

Absolute Zero

The temperature (0 degrees Kelvin) of an object defined by the theoretical condition

where the object has zero energy.

Accuracy

Maximum deviation, expressed in temperature units, or as a percentage of the

temperature reading, or as a percentage of the full scale temperature value, or as a

percentage of the target temperature, indicating the difference between a temperature

reading given by an instrument under ideal operating conditions, and the temperature of a

calibration source (per the ASTM standard test method E 1256-88).

Ambient Derating

Refer to Temperature Coefficient.

Ambient Operating Range

Range of the ambient temperature conditions over which the thermometer is designed to

operate.

Ambient Temperature

Ambient temperature is the room temperature or temperature surrounding the instrument.

Ambient Temperature Compensation (TAMB)

Refer to Reflected Temperature Compensation.

ASTM

ASTM is an abbreviation for American Society for Testing and Materials.

Atmospheric Windows

The Atmospheric Windows is the infrared spectral bands in which the atmosphere best

transmits radiant energy. Two predominant windows are located at 2 to 5 µm and at

8 to 14 µm.

Background Temperature

Temperature behind and surrounding the target, as viewed from the instrument.
