ELECTRICITY AT the PRIMARY LEVEL
DC Voltage - against a Josephson primary standard
DFM calibrates DC voltages under accreditation against the Danish Josephson primary standard in the range -10 V to 10 V.
The calibration uncertainty (CMC) ranges from 40 nV at voltages below 1 V to 370 nV at a voltage of 10 V.
Our services include
- K02.001, Calibration of a voltage reference standard (Zener), under accreditation
- K02.999, Electrical measurement/calibration according to quotation
In addition to the primary DC voltage calibrations DFM carries out secondary calibrations of DC voltage, resistance and current.
These secondary calibrations are often carried out as a part of the calibration of temperature equipment by our Thermometry team. For the benefit of our customers, we provide these secondary calibrations over selected ranges for other types of equipment, too.
The Measurement capability (CMC) is found here at the DANAK web pages.
