Simple and reliable system for accurate maintenance of voltage standards

A new automatic system is described whereby precise, simple and reliable intercomparison of electronic voltage standards is enabled by using a self-developed 16 channel low-thermal switch and digital nanovoltmeter, controlled by the computer. It enables faster and easier comparison, as well as optimisation of the whole procedure. The control software was developed using a LabVIEW, and the obtained parameters are pointed out.
