Calibration
You are in possession of a measuring instrument for which the metrological conditions of measurement are de-
fined in the specifications of this manual. Climatic and environmental conditions limit the specifications of your
instrument. SEFRAM checks the characteristics of each instrument individually on an automatic rack during man-
ufacture. Adjustment and verification are guaranteed within the framework of ISO9001 certification by measuring
instruments connected to COFRAC (or equivalent in ILAC reciprocity). The advertised characteristics are deemed
stable for a period of 12 months from first use, under normal conditions of use. We recommend checking after
12 months, without exceeding 24 months of use. Then every 12 months beyond 24 months. When checking
characteristics, it is advisable to respect average climatic conditions (23°C +3°C - 50(+20)%RH) and to operate
your equipment for 30 minutes beforehand. We advise you to have this verification carried out by our After-Sales
Service to ensure the best possible service and preserve the measurement quality of your instrument. When a
product returns to SEFRAM or B&K Precision, a full service is provided, including an internal upgrade to keep
pace with the latest developments, and a software upgrade. In the event of any deviation from specifications, your
instrument will be adjusted to regain its original characteristics.
