NOTE

• Notice the difference between error in the test and a failed result! An error is caused by

an abnormal termination during the operation of the test, whereas a failed result

indicates that the test results were not within the specified limits.

• Often it is only a damaged blank nut (poorly shaped from over tightening) that causes

the test to fail. Before investigating any other possible sources of failure make sure that

the blank nut you are using is in a good condition and properly tightened.
