The principle
Every electronic measuring device will only give correct results if it is checked regularly, i.e. calibrated correctly and adjusted when required. An electronic Balance, test weight or another measuring device is only a reliable measuring and checking tool if it is calibrated and this calibration is documented as part of a Quality procedure.
DAkkS calibration (DAkkS = German accreditation point) documents traceability to the national standard and this then meets the Standard requirements of QM Systems. DAkkS calibrations are valid internationally.
Only an accredited calibration laboratory can issue DAkkS calibration certificates. This defines not only the measuring method, but also gives information on tracing the test means to a national standard and the relevant measuring uncertainty is given.
