Echo-Echo Verify Mode – Thru-Verify (E-EV)
The echo-echo verify mode measures between 3 reflections. Similar to E-E mode,
this technique is commonly used to eliminate errors from surface coatings and also to
make measurements in multiple layered materials. The primary benefit of this mode,
is that a comparison is made, between the 2
jump has not occurred, providing an additional level of confidence to the
measurement. The disadvantage is that 3 reflections are needed which requires the
use of gates with controllable thresholds to adjust for sensitivity over a given
measurement range.
Pulse Echo Coating Mode – Coating On (PECT)
A custom hybrid combination mode using properties from the basic modes along with
a group of special techniques and theoretical wave phenomena's to measure coati ng
and material thicknesses at the same time, while still retaining the ability to locate
flaws and pits in materials. Therefore, the best description for this hybrid mode is
Pulse-Echo Coating mode.
