ECHO
WINDOW Echo detect gate which begins at
end of MB (main bang) blank in
mode 1 or interface echo in
modes 2 and 3. The value reported
for the end of echo window is
relative to the main bang. 0 ns to 224.71 μ s. 55 ns or MB blank
time interval, whichever is less.
ECHO 1
DETECT Detection polarity of first echo + or −
ECHO 2
DETECT Detection polarity of second echo + or −
IF BLANK Blank after interface echo 0 μ s to 20 μ s
M3 BLANK Blank after first measured back-
wall echo in mode 3 0 μ s to 20 μ s
VELOCITY Ultrasonic sound velocity of
material to be measured 0.508 mm/ μ s to 18.699 mm/ μ s
(0.0200 in./ μ s to 0.7362 in./ μ s)
ZERO Zero calibration factor 0.00 to 999.99
