Recalibrating the Unit
EXFO manufacturing and service center calibrations are based on the
ISO/IEC 17025 standard (General Requirements for the Competence of
Testing and Calibration Laboratories). This standard states that calibration
documents must not contain a calibration interval and that the user is
responsible for determining the re-calibration date according to the actual
use of the instrument.
The validity of specifications depends on operating conditions. For
example, the calibration validity period can be longer or shorter depending
on the intensity of use, environmental conditions and unit maintenance, as
well as the specific requirements for your application. All of these elements
must be taken into consideration when determining the appropriate
calibration interval of this particular EXFO unit.
Under normal use, the recommended interval for your FTB-610 Advanced
WB Copper Test Module is: 2 years.
For newly delivered units, EXFO has determined that the storage of this
product for up to six months between calibration and shipment does not
affect its performance (EXFO Policy PL-03).
