  • Page 2 Thank you for buying a SEFRAM recorder and for your trust in our company. The main goal of our various teams (research department, production, commercial, after-sales…) is to meet your requirements as much as possible by designing or updating high tech products.
  • Page 3 What to do in case of malfunction? In case of malfunction or for any problem of use, please contact the SEFRAM Instruments & Systems after-sales service. A technician will take your call in charge and will provide you any required information to solve your problem.
  • Page 4 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).
