Series 7334
AC/DC Resistance Standards
Very High Stability Calibration Laboratory Standards
G uildline 7334 series of Resistance Standards are designed
as very high stability calibration laboratory standards for
high accuracy resistance calibration in air, without the need for
stabilization in a temperature controlled bath. These standards
are suitable for both AC and DC applications.
They can be used as working standards or highly reliable and
rugged transportable transfer standards. They are extremely
useful for the calibration of resistance ranges of multi-function
calibrators and high accuracy DVMs, as well as being used in
more classical standards and calibration in resistance and
temperature measurements.
Hysteresis error, is typically better than negligible to 0.1 ppm
when stressed at three times the maximum voltage, and less
than 0.3 ppm over a temperature cycle between 0 0C and 40 0C.
Connections to these resistance standards are made via the
gold plated 5-way binding posts. In DC measurement, these
gold plated binding posts yield the lowest thermal EMF when
connected with gold, copper or silver.
The 7334 Series Precision Resistance Standards
are true AC/DC standards with minimal AC/DC
error up to1 kilo-Hertz, and are available in a
wide range of off the shelf and custom values

The impedance of the resistor is expressed as:
Z(f) = R(f)
