Check whether the head wave of each test point is
interpreted correctly , if not, reinterpret it manually.

If phase reversal occurs in the head wave of a certain test
point, right click mouse and select “set phase reversal point”
in pop-up menu;

If manual calculation is required, select “Manul calculation”
option in crack information area and manually screen the

Click “Processing-Calculate crack depth”:
a) If phase reversal in head wave is found in
crossing-crack test, take the average value of this
test distance and calculation results of two
adjacent test distances as crack depth.
b) If phase reversal in head wave is not found in
crossing-crack test, calculate crack depth value
and average value corresponding to all test
distances, delete test distance less than average
value or more than three times of average value,
then the average value of calculation results of
remaining test distances is crack depth.
