Parameter Value
Measurement modes Standard dual element : Time between excitation pulse and
first back-wall echo using dual element transducer.
Dual echo ‑ to ‑ echo : Time between successive back-wall
echoes using dual element transducers.
Thru ‑ coat : Time between excitation pulse and first back-wall
echo while ignoring or displaying a coating thickness.
Mode 1 : Time between excitation pulse and first echo
following blank period using contact transducers.
Mode 2 : Time between the interface echo and the first back-
wall echo. Normally used with delay line or immersion
transducers.
Mode 3 : Time between a pair of back-wall echoes following
the interface echo. Normally used with delay line or
immersion transducers.
V-path correction Automatic or manually created, dependent on transducer
type
