Probe Zero
Twin element probes are zeroed in the air without the need of
a zero block. The user is prompted to zero the probe at power
up and after a probe change.
Single element probes in multiple echo mode do not need to
be zeroed.
Measurement Modes
Single Echo mode with Twin element probe. Measures
thickness using the time from the delay line (zero point) to the
first back-wall echo. (UT Mode 2)
Echo-Echo mode with Twin element probe. Measures thickness
using the time between the first and second back-wall echoes.
(UT Mode 3)
Multiple Echo using Single element probe. Uses three matched
and verified back-wall echoes to determine the material
thickness and ignore surface coatings.
Resolution
