Abstract
PURPOSE: To simply perform the adjustment and setting work for each part based on test piece in a short time, by using the data related to the standard flaw formed artificially to flaw detecting repetitively.
CONSTITUTION: The test piece 15 having the standard flaw A and the flaw B greater than it artificially is found for the flaw with the detector 1 of eddy current flaw detector, and the balance output based on the detected output is sequentially in A/D conversion 8 and stored 9. In this memory, the oldest data is thrown away and the new data is sequentially taken. Further, the renewal of the stored data is stopped with the detection of the flaw B when the data of the flaw A is stored, the output of the memory is in D/A conversion 10, and it is repetitively outputted for the adjusting flaw signal of the eddy current flaw detector.
