MTL VEL = velocity of sound in
test material; reference value
only (not intended for precision
velocity measurement).
When in
coarse mode,
“MTL VEL” (upper case) is
displayed.
When in
fine mode “mtl vel”
(lower case) is displayed.
DELAY adjusts timing of sweep
start and, thus, horizontal position
of signals, gate ,etc. in A-scan
display.
Coarse : 2 user selectable
values; factory settings are
.2330 and 1320 in/
µs (10
