Power Diagnostix operates a calibration laboratory, which has received the accreditation within the German Calibration Service DKD by 2003. The audit was held by ‘Physikalisch Technische Bundesanstalt’ (PTB), the German authority of standards. In January 2012, Power Diagnostix passed to the newly introduced German accreditation authority DAkkS (DAkkS = Deutsche Akkreditierungsstelle). Power Diagnostix’ new accreditation is filed under D-K-15068-01-00. The accreditation covers impulse charges (pC), voltages, and timing parameters, as well as on-site calibration of voltages up to 500 kVAC. The DAkkS calibration service is of course also available for instruments and calibrators of other vendors.
