Beschreibung

The IET Labs 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.
Three-Terminal: The GenRad 1422-CD are three terminal capacitors with shielded coaxial terminals for use in three-terminal measurements. The calibrated direct capacitance is independent of terminal capacitances to ground, and losses are very low.
