Certification

All probes or gages are shipped with a Certificate of
Calibration. For organizations with re-certification
requirements, gages may be returned at regular
intervals for calibration. DeFelsko recommends that
customers establish gage 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.

Operation Overview

Operation Overview

1. Turn the Gage ON (see Power-Up pg.2)
2. ZERO the probe (see pg.5)
3. ADJUST to a known thickness, if necessary
(see pg.8)
4. MEASURE the part (see pg.5)

Couplant

Couplant

Couplant is required to propagate ultrasound into the
coating. Water is a good couplant for smooth
coatings. Use the supplied glycol gel for rougher
coatings. While it is unlikely that the couplant will
damage the finish or leave a stain on the surface, we
suggest testing the surface by using the couplant on
a sample. If testing indicates that staining has
occurred, a small amount of water can be used
instead of couplant. Consult the Material Safety Data
Sheet available on our website and your coating
supplier if you suspect the couplant may damage the
coating. Other liquids such as liquid soap may also
be used.
