T
temperature
coefficient
the percentage that a measurement will vary according to temperature.
See also thermal drift.
thermal drift measurements that change as the temperature varies
thermal EMFs thermal electromotive forces—voltages generated at the junctions of
dissimilar metals that are functions of temperature. Also called
thermoelectric potentials.
