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.
Automatic or manually created, dependent on transducer
type
Selectable from the keypad:
LOW: 0.1 mm (0.01 in.)
