Series 9334A

Resistance Standards
Very High Stability Calibration Laboratory Standards


G uildline 9334A 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.
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 laboratory
applications.
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 by conventional
4-terminal connection up to 1M and two terminal
connection for values above 1M . The model 9334AH-1G and
the 9334AW-1G are designed to answer a difficult calibration
need for owners of the HP/Agilent 3458A and the
Wavetek/Datron 1271 and 1281 model DMMs.
