Definition

1. Portion of the measurement signal caused by a temperature-induced change in resistance of a strain gage that is independent of, and unrelated to, the mechanical strain in the test part. 2. The reversible part of the temperature-induced strain of a strain gage installed on an unrestrained test specimen when exposed to a change in temperature.
