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

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

thermoelectric
potentials

See thermal EMFs

thermal EMFs

thermal electromotive forces—voltages generated at the junctions of 
dissimilar metals that are functions of temperature. Also called 
thermoelectric potentials.

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
