Properties:

An item designed to produce an alternating current, direct current, and electromotive force with high degree of accuracy. It serves as a standard of calibration for ammeter(s), voltmeter(s), wattmeter(s), and similar devices that require accurate voltage and/or current inputs for calibration purposes. See also voltage standard. For items whose outputs are used to operate other electrical or electronic equipment, see power supply.
