PROBLEM TO BE SOLVED: To correlate the measurement result of an IC by an IC tester with the classification result by an auto-handler. SOLUTION: The IC tester 1 adds the measurement number characteristic to each lot to the measurement result to be transmitted to the auto-handler 2 and transmits the result, and produces a measurement result file storing measurement data of each IC. The auto-handler 2 produces a classification result file storing classified data of each classified and stored IC based on the measurement number transmitted from the IC tester 1 and category information. The IC tester 1 transfers the produced measurement result file and classification result file to a host computer 3 in each lot, and the host computer 3 memories and controls transferred both files.
