METROLOGY
The metrological conditions of your measurement instrument are defined in the specifications
of this notice. Climate and environmental conditions restrict the specifications of your
recorder. SEFRAM checks the characteristics of each appliance one by one on an automatic
bench during its manufacture. The adjustment and control are guaranteed under conditions of
the ISO9001 certification by facilities in connection with the COFRAC (or equivalent in the
context of ILAC reciprocity).
The specified characteristics are considered stable for a period of 12 months of use, and under
normal conditions of use.
We recommend a check after 12 months and max. 24 months of use, then every 12 months
after 24 months.
For any check of the characteristics, the following average climate conditions shall be
maintained (23°C +3°C – 50(+20) %RH). The recorder should have been working for 0.5
hour before check.
We recommend that you have this control made by our after-sales service (Service Après-
Vente) for the best service and preservation of the measuring quality of your instrument.
When a recorder returns to SEFRAM, maximum service is provided with internal updating
according to the required adjustments and software updates. In case of shift in the
characteristics, your instrument shall be adjusted to recover its original characteristics.
