GenRad IET LABS 1689-9604 Calibration Kit for Digibridges

Description

GenRad IET LABS 1689-9604 Calibration Kit for
Digibridges
Calibration Kit For the 1659, 1689, 1692, 1693 Digibridges. 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.
An ISO-17025 Accredited calibration chart is provided with R
& Q values for each resistor.

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°..
The item was recently calibrated by IET Labs and includes
data/paperwork (not shown).
