The 1422CL is a used Capacitance Standard from General Radio. Engineers use direct current (DC) voltage standards to calibrate, standardize, normalize, and monitor drift, verify linearity, and establish regulation in electronic equipment. Standards are important during electronics compliance testing. Phase angle standards are ideal for calibrating many different electronics, including power analyzers, vector voltmeters, phase meters, phase sensitive instruments, and resolvers.
The 1422CL Precision Capacitor is a stable and precise variable air capacitor intended for use as a continuously adjustable standard of capacitance. One of the most important applications is in AC bridge measurements, either as a built-in standard or as an external standard for substitution measurements.
