ABSTRACT:
Automation in measurement has wide range of electrical metrology
applications and construction of powerful calibration software is one of the
highly accurate metrological laboratories’ priorities. Thus, two automatic
systems for controlling and calibrating the electrical reference standards have
been established at National Institute for Standards (NIS), Egypt. The first system has been
built to calibrate the zener diode reference standards while the second one has
been built to calibrate the electrical sourcing and measuring instruments. These
two systems act as the comprehensive and reliable structure that, from the
national electrical standards, disseminates the traceability to all the electrical
units under calibration. The software of the two systems has been built using
the Laboratory Virtual Instrument Engineering Workbench (LabVIEW) graphical
language. The standard
development procedures have been followed in the building of both systems
software. The software requirement specifications as well as functional
specifications are taken into consideration. Design, implementation
and testing of the software have been performed. Furthermore, software
validation for measurements’ uncertainty as well as results’ compatibility in
both automatic and manual modes has been achieved.
