State primary standard for the unit of direct current, the ampere
Measurement Techniques, 1995The new state primary standard for direct current is described, together with its block diagram and accuracy parameters. The accuracy of realization is improved by two orders of magnitude (standard deviation 5–10−8, residual systematic error 2·10−7). The range of current realization in the standardis extended to 10−16 A.

A primary standard of voltage maintained in solid-state references
IEEE Transactions on Instrumentation and Measurement, 1987In September 1984, the 54 saturated standard cells which had been used to maintain the Fluke corporate volt were removed from service and placed in storage. Since that time, Fluke's corporate volt has been maintained in 4 solid-state, 10-V references. Discarding the cells has much reduced the time and cost of maintaining the standard, has significantly
