The IET Labs GenRad 1423-A decade capacitor is a versatile tool for calibration laboratories and production-line testing. With it a bridge can be standardized to an accuracy exceeded only by that of the highest quality, individually certified laboratory standards such as the GR 1404 Reference Standard Capacitors.
Used with a limit bridge, such as the GR 1689 Digibridge, the 1423 facilities fast and accurate production-line measurements of arbitrary capacitance values with minimum setup time.
Any value of capacitance from 100 pF to 1.111 ;.F, in steps of 100 pF, can be set on the four decades and will be known to an accuracy of 0.05%. The terminal capacitance values are set precisely to the nominal value and can be readjusted later at calibration intervals, if necessary, without disturbance of the main capacitors. The 1423-A decade capacitor consists of four decades of high-quality silvered-mica capacitors similar to those used in the GR1409 Standard Capacitors. The capacitors and associated switches are mounted in an insulated metal compartment, which in turn is mounted in a complete metal cabinet. This double-shielded construction ensures that capacitance at the terminals is the same for either the three-terminal or the two-terminal method of connection (except for a constant difference of about one picofarad). This external capacitance can be included in the two terminal calibration by the adjustment of a single trimmer.
