6.3 Calibration and adjustment service
6.3.1 Certificates
The certificates are categorised as ISO calibration certificates and DAkkS calibration
certificates. The purpose of the calibration is to verify the precision of the measuring
device by comparing it with a traceable reference.
NOTE
The ISO standard 9001 is applied for the calibration certificates. These certificates
area affordable alternative to the DAkkS calibration certificates and provide informa-
tion of the traceable reference, a list of individual values and documentation.
NOTE
The DAkkS calibration is based on DIN EN ISO/17025, the accreditation basis recog-
nised worldwide. These certificates offer high-quality calibration and consistently high
quality. DAkkS calibration certificates can only be issued by accredited calibration
