Beschreibung
Zusammenfassung:	A system for reproducing and transferring the units of impedance parameters, including a set of precision automatic comparators and thermostatted measures-carriers is described. The apparatus enables the dimensions of any parameters of impedance to be transferred for any value of the loss tangent or phase angle over a whole range of values of impedance, to reproduce the unit of inductance in terms of the units of capacitance and frequency, and to compare the impedances of the standards of capacitance and resistance at frequencies of 1.0 kHz and 1.59 kHz.
