With it a bridge can be standardized to an accuracy exceeded only by that of the highest quality, indi- vidually cer fi ed laboratory standards such as the GR 1404 Reference Standard Capacitors. When used with the GR/IET 1689 Digi- bridge, the 1423 facilitates fast and ac- curate produc on-line measurements of arbitrary capacitance values with minimum setup  me. Any value of capacitance from 100 pF to 1.111 µF in steps of 100 pF, can be set on the four decades and will be known to an accuracy of ±0.05%, see specifi ca ons. The terminal capacitance values are set precisely to the nominal value and can be readjusted later at calibra on inter- vals, if necessary, without disturbance of the main capacitors. The 1423 consists of four decades of high-quality silvered- Nominal Values: 100 pF to 1.111 µF in steps of 100 pF Accuracy: 100 pF per step decade: ±(0.15% + 0.5 pF) All other decades: ±(0.05% + 0.05 pF) Stability: ±(0.01% + 0.5 pF) Calibration temperature: 23°C ±1°C Dissipation Factor: Not greater than 0.001, 0.0005, and 0.0003 for capacitances of 100 to 1000 pF, 1100 to 2000 pF, and 2100 pF to 1.1110 µF respectively mica capacitors similar to those used in the GR 1409 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 construc on ensures that capacitance at the terminals is the same for either the three-terminal or the two- terminal method of connec on (except for a constant diff erence of about one picofarad). This external capacitance can be included in the two terminal calibra on by the adjust- ment of a single trimmer values are known to an accuracy typically ±0.01 %, determined and maintained in terms of reference stan- dards periodically calibrated by and SI.
