Certification
PosiTector
RTR
probes include a Certificate of Calibration showing
traceability to a National Metrology Institution. For organizations with
re-certification requirements, instruments may be returned at regular
intervals for calibration. DeFelsko recommends that customers
establish 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.
Written Calibration Procedures are available online at no charge.

Prepare the test surface
Locate a representative site for
measurement. Clean the surface to be
tested.
DeFelsko recommends the use of the
included putty to remove dust, debris, or
residual blast media from the surface.
Firmly press the putty onto the surface
using your fingers, and remove.
Burnish the replica tape
(create a replica)
Select the appropriate grade of replica tape based on the target profile.
See tape instructions for assistance.
Pull a single adhesive-backed replica tape free of its release paper.
A "bull's eye" circle of paper should remain on the release paper (it is
not used for measurement). Apply replica tape to blasted surface.
Press the adhesive-backed ends of the paper to hold it firmly in place
during the burnishing process.
