Performing a Mix
Calibration
1 – When included by a workflow’s architect, the Mix
feature allows one or more indications to be subtracted
from the Primary channel’s view. The Secondary channel
(called Subtract in the example) frequency must be
different from the Primary and is typically set to about ¼
of the Primary.
2 – Acquire a buffer of data from a calibration standard
that includes flaws as well as an undesired indication
that needs to be subtracted. The undesired indication
might come from a tube support ring in a tubing test,
or perhaps a rivet in a lap splice joint test. This top strip
chart shows the Primary channel’s view.
3 – Freeze the instrument with both flaw and undesired
indications on the time base (strip chart) views. In
this case the center strip chart shows the Secondary
channel’s view.
4 – Undesired indication to be removed (or subtracted)
from the Primary view.
5 – The Mix view includes the arithmetical subtraction of

Dynamic Gain
Compensation (DGC)
1 – The DGC (dynamic gain compensation)
process applies increased gain to account for an
increase in coating thickness. The intention of this
gain application is to make signals from equal
indications, which occur below varying thicknesses
of coating, appear equal in amplitude.
2 – Raw measurement data channel (indication
signal)
3 – This plot displays the coating thickness channel,
as defined by the workflow’s architect. The lissajous
is currently displaying the liftoff signal.
4 – Acquired data with DGC applied
5 – After touching either Calibration button and
launching the process, follow the on-screen
instructions. These will require that you repeatedly
scan the same notched calibration standard while
inserting additional shims (meant to simulate
coating thickness). Note that the test part’s coating
and shim applied to your calibration standard need
not be made from the same material. However,
both the test part’s coating and the shim material
must be non-conductive and non-magnetic.
Note: Press and hold the CAL button to cancel the
process.

Evaluating conductivity when coating thickness exceeds

Conductivity Evaluation
Conductivity evaluations rely on a calibration process using two samples
with known characteristics. Conductivity can be measured through nonmagnetic coatings (such as paint). The evaluation process compensates for
test temperatures that vary moderately from the calibration temperature.
The conductivity-averaging feature allows for the collection of multiple
samples from a known-good material, followed by the evaluation of test
parts against the known-good average.
