Technical Data
The PosiTest AT is shipped with a Certificate of Calibration
showing traceability to a national standard. For organizations with
re-certification requirements, the PosiTest AT may be returned at
regular intervals for calibration. DeFelsko recommends that our
customers establish their instrument calibration intervals based
upon their own experience and work environment. Based on our
product knowledge, data and customer feedback, a one year
calibration interval from either the date of calibration, date of
purchase, or date of receipt is a typical starting point.
