The simple way to maintain anddisseminate your volt
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.
