| 2. Principle |
At the beginning of the test, choose a test method, estimate
an initial mass and ^m. Test, if the first specimen is failure,
decrease the mass of the falling dart by decreasing poise of
^m. If the first specimen is not failure, add the mass of the falling dart by increasing poise of ^m. Test as the
same. In brief, increase or decrease the ^m according to whether the former specimen is failure or not. After
20 specimens, calculate the total number of failure specimens N. If N equals to 10, test over. If N is less than
10, add specimen and continue to test until N is equal to 10. If N is more than 10, add specimen and continue
the test until the number of non-failure specimen is 10. Then calculate the test results according to special
formula.

| 3. Operation demo |
Power on -> choose test method -> estimate initial impact mass and ^m -> increase or decrease the ^m
according to impact result -> system calculates automatically -> estimate whether the results satisfy the
condition of stopping -> display test results -> print test results -> test over
