Temperature Resolution

The minimum simulated or actual change in target temperature that gives a usable change in output and/or indication (per the ASTM standard test method E 1256-88).

Thermal Shock

A short-term error in accuracy caused by a transient ambient temperature change. The instrument recovers from its accuracy error when it comes back into equilibrium with the new ambient conditions.

Time Constant

The time it takes for a sensing element to respond to 63.2% of a step change at the tar-get.

Transfer Standard

A precision radiometric measurement instrument with NIST traceable calibration in the USA (with other recognized standards available for international customers) used to calibrate radiation reference sources.

Transmittance

The ratio of IR radiant energy transmitted through an object to the total IR energy received by the object for any given spectral range; the sum of emittance, reflectance, and transmittance is unity.

Warm-Up Time

Time, after turn on, until the instrument will function within specified repeatability (per the

ASTM standard test method E 1256-88).
