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 = Date of first usage (if less than six months 
after the calibration 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.
