| The simple way
to maintain and disseminate your volt
The 732B is a direct
voltage standard with 10V and 1.018V outputs. The 734A
is a direct voltage reference standard that consists of
four 732Bs that are mechanically and electrically
isolated, housed in a rack-mountable enclosure.
The 734A is designed to be
a primary voltage standard for primary and secondary
calibration and standard laboratories. Because it is
made up of four independent standards, intercomparisons
of the standards and statistical methods can be used to
reduce the uncertainty of the reference significantly
over time.
Because each 732B is
independent, it can be removed from the 734A and used as
a portable standard to transfer a value from the primary
734A reference to remote service or production locations
for traceability, without disturbing the primary
reference.
The 734A is the only
standard of its type that meets the design requirements
of Technical Note NBS 1239, published by the U.S.
National Institute of Standards and Technology in 1987.
