Abstract

This Paper gives a summary of a completely automated system that was developed for the high accuracy calibration of multifunction measuring instruments (like the Fluke 5720A calibrator or HP3458A multimeter, for example). The system is capable of calibrating all the functions (ranges: Vdc: 10 mV ... 1 kV; Vac: 2 mV ... 1 kV; Idc: 10 µA ... 2 A; Iac: 10 µA ... 2 A) of digital calibrators and multimeters at very high accuracy. Additionally, efficiency and facility of operation are characterizing the system, which became a powerful tool in electrical metrology.
