S samples
sense in four-wire resistance the sense measures the voltage across the resistor
being excited by the excitation current
settling time the amount of time required for a voltage to reach its final value within
specified limits
S/s samples per second—used to express the rate at which an instrument
samples an analog signal
system noise a measure of the amount of noise seen by an analog circuit or an ADC when
the analog inputs are grounded
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.
thermoelecótric
potentials
See thermal EMFs.
transfer rate the rate, measured in bytes/s, at which data is moved from source to
destination after software initialization and set up operations; the maximum
rate at which the hardware can operate
