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 OTDR is: one year.

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).
