Recalibrating the Unit
To help you with calibration follow-up, EXFO provides a special calibration
label that complies with the ISO/IEC 17025 standard and indicates the unit
calibration date and provides space to indicate the due date. Unless you
have already established a specific calibration interval based on your own
empirical data and requirements, EXFO would recommend that the next
calibration date be established according to the following equation:
Next calibration date = Shipping date+ Recommended calibration
period (2 years)
To ensure that your unit conforms to the published specifications,
calibration may be carried out at an EXFO service center or, depending on
the product, at one of EXFO’s certified service centers. Calibrations at
EXFO are performed using standards traceable to national metrology
institutes.
Note: You may have purchased a FlexCare plan that covers calibrations. See the
Service and Repairs section of this user documentation for more
information on how to contact the service centers and to see if your plan
qualifies.
