absolute zero . The temperature of –273.16 °C, or –459.69 °F, or 0 K, thought to be the temperature at which molecular
motion vanishes and a body would have no heat energy.
accuracy . The degree of correctness with which a measured value agrees with the true value.
electronic accuracy . The accuracy of an instrument independent of the sensor.
sensor accuracy . The accuracy of a temperature sensor and its associated calibration or its ability to match a standard
curve.
Alumel™ . An aluminum-nickel alloy which comprises the negative lead of a Type K thermocouple.
American Standard Code for Information Exchange (ACSII) . A standard code used in data transmission, in which
128 numerals, letters, symbols, and special control codes are represented by a 7-bit binary number as follows:
American Wire Gage (AWG) . Wiring sizes are defined as diameters in inches and millimeters as follows:

ambient temperature . The temperature of the surrounding medium, such as gas or liquid, which comes into contact with
1
the apparatus.
ampere . The constant current that, if maintained in two straight parallel conductors of infinite length, of negligible
circular cross section, and placed one meter apart in a vacuum, would produce between these conductors a force equal
–7
to 2 × 10 newton per meter of length.
ampere-turn . A MKS unit of magnetomotive force equal to the magnetomotive force around a path linking one turn of a
conducting loop carrying a current of one ampere; or 1.26 gilberts.
ampere/meter (A/m) . The SI unit for magnetic field strength (H). 1 ampere/meter = 4 π /1000 oersted ≈ 0.01257 oersted.
analog controller . A feedback control system where there is an unbroken path of analog processing between the
feedback device (sensor) and control actuator (heater).
analog data . Data represented in a continuous form, as contrasted with digital data having discrete values.
analog output . A voltage output from an instrument that is proportional to its input. For example, from a digital voltmeter,
the output voltage is generated by a digital-to-analog converter so it has a discrete number of voltage levels.
anode . The terminal that is positive with respect to the other terminal when the diode is biased in the forward direction.
asphyxiant gas . A gas which has little or no positive toxic effect but which can bring about unconsciousness and death
by displacing air and thus depriving an organism of oxygen.
