Pressing [2nd F], [CAL VEL] (VEL) opens the VELOCITY screen where you can see
and edit the calibrated metal sound velocity. Pressing [2nd F], [CAL VEL] (VEL) again
opens the VELOCITY screen for the calibrated sound velocity through the coating.
5.6 Echo Detection Modes with Dual Element Transducers
With dual element transducers, the 38DL PLUS offers three echo detection modes
allowing you to measure thicknesses in various material conditions. A description of
each of the three echo detection modes (STANDARD, AUTO E‑TO‑E, and MANUAL
E‑TO‑E) follows:
STANDARD
The standard echo detection mode measures the thickness based on the time of
flight between the main bang to the first back-wall echo. Use this mode for
uncoated materials with good echo waveforms.
The DE‑STD indicator appears to the left of the thickness reading and a
triangular echo detection marker appears at the back-wall echo below the
waveform display (see Figure 5-12 on page 80).
