6.6 REPAIR AND CALIBRATION
To ensure that your instrument meets factory specifications, we recommend
that it be scheduled back to our factory Service Center at one-year intervals for
recalibration or as required by other standards or internal procedures.
For instrument repair and calibration:
You must contact our Service Center for a Customer Service Authorization
Number (CSA#). This will ensure that when your instrument arrives, it will be
tracked and processed promptly. Please write the CSA# on the outside of the
shipping container. If the instrument is returned for calibration, we need to know
if you want a standard calibration or a calibration traceable to N.I.S.T. (includes
calibration certificate plus recorded calibration data).
