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 iso-calibration certificates. These certificates
area affordable alternative to the DAkkS calibration certificates and provide infor-
mation 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 is rec-
ognised worldwide. These certificates offer high-quality calibration and consistently
high quality. DAkkS calibration certificates can only be issued by accredited calibration
laboratories which have demonstrated their expertise in accordance with DIN EN
ISO/IEC 17025. The DAkkS calibration includes any necessary adjustment with the
purpose of minimising a deviation of the measuring device.
DAkkS calibration certificates are accompanied with a list of individual measurements
before and after the adjustment, documentation and, if applicable, graphic representa-
tion, calculation of the expanded measuring uncertainty and traceability to the national
standard.
NOTE
The product is delivered with a test report. This confirms that the measuring device
has been adjusted and tested.
NOTE
Only the manufacturer can check the basic settings and make corrections if neces-
sary.
