parameter.
4. Use the [] and [] keys to adjust the value to exclude unwanted peaks and
detect the desired echoes.
5.6.2 Dual Element Transducer Selection in Echo-to-Echo Modes
Although the echo-to-echo modes work with all of the 38DL PLUS dual element
transducers, Olympus recommends using particular transducers for specific thickness
ranges in steel parts (see Table 3 on page 84).
