What is traceability?

Traceability describes a process by means of which the measured value indicated by a measuring instrument can be compared to the national standard for the given measured quantity in one or several steps.

Traceability and organization of our DAkkS calibration lab (standards hierarchy)

Our permanent calibration laboratory has three primary tasks:

  • Establishment of a link to the German Federal Institute of Physics and Metrology (PTB)
  • Assurance of traceability of measured quantities to SI units
  • Calibration of working standards, as well as on-site calibration benches and test equipment monitoring

The on-site test benches assigned to the permanent calibration laboratory fulfill the following functions:

  • Calibration of measuring instruments and calibrators
    - Devices are calibrated at these test benches either during the course of final manufacturing inspection as a standard routine, or individually when service is required.
  • Calibration of special measuring equipment, for example:
    - Shunts by means of current-voltage method
    - High value resistance, 30 GOhm with
    a measuring voltage of 1000 V
