coefficient
the percentage that a measurement will vary according to temperature.
See also thermal drift.
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.
