Beschreibung
The GenRad 1422 is a ultra stable and precise variable primary air capacitor intended for use as a continuously adjustable standard of capacitance. One of the most important applications for the 1422 is in ac bridge measurements, either as a built-in standard or as an external standard for substitution measurements. The 1422 is available in a variety of ranges, terminal configurations, and scale arrangements to permit selection of precisely the required characteristics.
For convenience in making substitution measurements, the 1422-MD and 1422-ME are also dual-range two-terminal capacitors, with scales reading in capacitance removed.
