GenRad Quadtech IET Labs 1689-9604 Digibridge Calibration Kit 1689
A self-contained calibration kit used to calibrate IET Labs, GenRad, and QuadTech Digibridges. The 1689-9604 Calibration Kit plugs into the built-in test fixtures of the 1659, 1689 and 1692 and can be used with the 1689-9600 remote fixture on the 1689M and 1693.
Consists of four resistors, a precision open and precision short.Nominal Values: R1: 95.3 kΩ ; R2: 5.97 kΩ , R3 374 Ω , 24.9 Ω
Accuracy: 0.1% of nominal value
Stability: Better than 25 ppm per year
Temperature Coefficient 2°C ppm
Calibration Accuracy: These resistors are compared with a precision of 5 ppm to working standards whose absolute values are known to 10 ppm, as determined from reference standards whose absolute values are know to 10 ppm,as determined from reference standards periodically measured by NIST. The 1 kHz Q values are in parts-per million and are based on the D values of GenRad 1404 capacitors which have been shown to be less than 5 ppm, and the assumption that the difference between the inductance of a low -valued composition resistor and a wire of the same geometry is negligible. These Q values should be within 25 ppm at 1 KHz. All calibrations are made at 23° ± 2 C°..
